Answer:
To create a perfect square of given expression,
[tex]5x^2+15x[/tex]On solving the above expression we get,
[tex]=5(x^2+3x)[/tex]we have that,
[tex](x+a)^2=x^2+2ax+a^2[/tex]To create a perfect square: add ( half the coefficient of the x- term )²
Coefficient of x term is 3
half the coefficient of the x- term is 1.5
( half the coefficient of the x- term )² is 2.25
Add 2.25 to the quadratic expression inside the bracket, we get,
[tex]=5(x^2+3x+2.25)[/tex]In general, we adding 11.25 (that is, 2.25x5=11.25) to the given expression.
we get,
[tex]=5(x+1.5)^2[/tex]Multiply 5 to the above equation, we get
[tex]=5^2(x+1.5)^2[/tex][tex]=(5x+7.5)^2[/tex]Based on the above calculation, we adding 11.25 and multiplying the expression by 5 in order to create a perfect square.

Step-by-step explanation:
Up 6 right 4: (4,6)
Right 4 up 6: (4,6)
Left 4 up 6: (-4, 6)
Down 4 right 6: (6, -4)
Right 6 down 4: (6, -4)
Answer: Right 4 up 6 is (4,6), left 4 up 6 is (-4,6), and right 6 down 4 is (6, -4).
Step-by-step explanation: Since you're starting from the origin, it's mainly counting. For (4,6), you are moving 4 places from 0 on the x axis. Then you move up 6 spaces from 4 on the y-axis. If you didn't move up, you'd be stuck at (4,0). It's important to keep in mind that (x,y).
A normal distribution has = 32 and = 5.
(a) Find the z score corresponding to
x = 27.
(b) Find the z score corresponding to
x = 43.
(c) Find the raw score corresponding to
z = −3.
(d) Find the raw score corresponding to
z = 1.1.
a) z score corresponding to x = 27 is -1
b) z score corresponding to x = 43 is 2.2
c) Raw score corresponding to z = -3 is 17.
d) Raw score corresponding to z = 1.1 is 37.5
Given,
Normal distribution with μ = 32 and σ = 5
a) z score corresponding to x = 27
z = (x - μ) / σ
Then,
z = (27 - 32) / 5 = -5/5 = -1
That is, z score corresponding to x = 27 is -1.
b) z score corresponding to x = 43
z = (x - μ) / σ
Then,
z = (43 - 32) / 5 = 11/5 = 2.2
That is, z score corresponding to x = 43 is 2.2
c) Raw score corresponding to z = -3
z = (x - μ) / σ
Then,
-3 = (x - 32) / 5
-3 × 5 = x - 32
-15 = x - 32
x = 32 - 15 = 17
That is, raw score corresponding to z = -3 is 17.
d) Raw score corresponding to z = 1.1
z = (x - μ) / σ
1.1 = (x - 32) / 5
1.1 × 5 = x - 32
x = 32 + 5.5 = 37.5
That is, raw score corresponding to z = 1.1 is 37.5

On one day Fred’s Sports World sold 9 Buffalo Bills jerseys and 3 Miami Dolphin jerseys for a total of $899.40. The next day they sold 12 Bills jerseys and only 2 Dolphins jerseys for a total of $1139.30. How much is the Bills jersey and how much is the Dolphins jersey?
Given:
Let x be the cost of the Buffalo Bills jersey.
Let y be the cost of the Miami Dolphin jersey.
According to the question, we have
9x+3y=899.40.......(1)
12x+2y=1139.30.....(2)
From (1),

The impact of new entrants, new products, channel conflicts, and regulation would all be associated with the external opportunities and threats dimension of a SWOT website design analysis.
In summary, the impact of new entrants, new products, channel conflicts, and regulation are all factors that fall under the external opportunities and threats dimension of a SWOT website design analysis. 1. New entrants: When new companies enter the market offering similar website design services, it can increase competition and potentially affect the market share of existing website design businesses. This is an external threat as it poses challenges and risks to the current players in the industry. 2. New products: The introduction of new and innovative website design products can create opportunities for businesses to attract more customers and gain a competitive edge. This is an external opportunity that can be leveraged to improve market position.
3. Channel conflicts: Channel conflicts refer to conflicts or disputes that arise between different distribution channels. In the context of a SWOT analysis for website design, channel conflicts can impact how products and services are delivered to customers. For example, if a website design company relies heavily on a specific distribution channel and that channel experiences conflicts or disruptions, it can affect the company's ability to reach its target market. This is an external threat that needs to be considered.
4. Regulation: Regulations imposed by governing bodies can have a significant impact on website design businesses. For example, regulations related to data privacy, accessibility, or internet governance can affect how websites are designed and operated. Compliance with regulations is crucial to avoid penalties or legal issues. This is an external threat that businesses need to navigate.

A car that originally valued at $32,000 loses 18% of its value every 3 years. What will be the value of the car after 12 years?
The value of the car after 12 years is $15,229.50
Here, we want to calculate the value of a car that loses a percentage of its origial value after some years
To do this, we shall need an exponential equation that represents decay or depreciation
We can have this as;
[tex]P=I(1-r)^t[/tex]where;
P is the present value that we want to calculate
I represents the original value of the car which is $32,000
r is the percentage of decrease per year
From the question, there is a decrease of 18% every 3 years
The percentage decrease per year will be 18%/3 = 6%
6% is same as 6/100 = 0.06
t represents the time frame we are considering = 12 years
We proceed to input all these values into the equation above
We have it as;
[tex]\begin{gathered} P=32,000(1-0.06)^{12} \\ \\ P=32,000(0.94)^{12} \\ \\ P\text{ = \$15,229.50} \end{gathered}[/tex]In a quadrilateral, two angles are x°, two angles are (3x+8)°. What is x and the measures of the angles?

18. An 80-pound grass seed mixture is 30% bluegrass seed. How many pounds of seed
containing no bluegrass seed (0%) should be added to the seed mixture for a resulting
blend that is 20% bluegrass seed? Construct a table, then solve.
Step-by-step explanation:
what table is your teacher taking about ?
in any case this is resistive easy to solve
80 pounds of 30% with x pounds of 0% result in 80+x pounds of 20% :
80×0.3 + x×0 = (80 + x)×0.2 = 80×0.2 + x×0.2
80×0.1 = x×0.2
x = 80×0.1/0.2 = 80/2 = 40 pounds
so, 40 pounds of 0% have to be added to the 80 pounds of 30% to get a mixture of 20% (80+40 = 120 pounds).

Triangle ABC is shown below, with the angle measures as marked.
What is the measure of Angle A and B?
The measure of Angle A and Angle B are 54° and 122° respectively.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In triangle ABC,
The measure of angle A = (n + 20)°
The measure of angle B = (3n - 10)°
The measure of angle C = n°
Now,
The sum of all the angles of the triangle = 180°
So, we can formulate;
(n + 20)° + (3n - 10)° + n° = 180°
Solve for n as;
n + 20 + 3n - 10 + n = 180
5n + 10 = 180
5n = 180 - 10
5n = 170
Divide by 5, we get;
n = 170/5
n = 34
Thus, The measure of angle A = (n + 20)°
= 34 + 20
= 54°
And, The measure of angle B = (3n - 10)°
= 3 x 34 + 20
= 102 + 20
= 122°
Therefore,
The measure of Angle A and Angle B are 54° and 122° respectively.

Jaleel and Angela purchased a bag of sugar and used it evenly so the amount of flour that they each need, based on their brownie recipes are:
Angela - 5 cups of flour Jaleel - 6 ²/₃ cups of flourHow to find the amount of flour needed?Jaleel and Angela purchased a 20-cup bag of sugar and divided it evenly which means that they each get 10 cups of sugar.
The number of cups of sugar needed per cup of flour is:
= Change in sugar / Change in flour
= (3 - 1.5) / (2 - 1)
= 1.5 cups of sugar
The amount of flour needed would be:
= Number of cups of sugar / Cups of sugar per cup of flour
= 10 / 1.5
= 6 ²/₃ cups of flour
Angela's recipe shows that the cups of sugar needed per cup of flour is:
= (2 - 0) / (1 - 0)

Step-by-step explanation:
You want DF when L is the midpoint, LD = x-3 and LF = 2x-8.
Congruent segmentsSegments DL and LF are marked the same, so are congruent. Using the given expressions, we have ...
LF = LD
2x -8 = x -3
x = 5 . . . . . . . . add 8-x to both sides
Then the measures of the segments are ...
LF = 2(5) -8 = 2
LD = 5 -3 = 2
DF = DL +LF = 2 +2 = 4
The length of DF is 4 units.
What number should be subtracted from both sides of the following equation to solve for x?x + 27 = 303027573
Step 1
Given;
[tex]x+27=30[/tex]Required; To solve for x
Step 2
Add -27 to both sides
[tex]\begin{gathered} x+27-27=30-27 \\ x=3 \end{gathered}[/tex]Answer; The number that should be subtracted from both sides of the equation is 27
