If neither a nor bare equal to zero, which answer most accurately describes the product of (a + b)(a - b)?
Answer:
a² - b²
Step-by-step explanation:
We can recognize (a + b)(a - b) as a difference of squares.
Step 1: Write expression
(a + b)(a - b)
Step 2: FOIL (Expand)
a² - ab + ab - b²
Step 3: Combine like terms
a² - b²

Step-by-step explanation:
) The price of a watch is marked Rs 11,250. When it is sold allowing 20% discount,
20% profit is made. By what percent is the discount to be reduced to increase the
profit by 3%?
Step-by-step explanation:
the first step is to find the cost price
when 20% discount=
11250*80/100= 9000
the 20% discounted price is 9000
there is still a 20% profit in this 20% discount
so Cost.Price *120/100=9000
Cost price= 7500
now its asking for discount percentage at 3% profit so first calculate price after 3% profit
7500*103/100= 7725
so discount on rs11250 required to produce 3% profit=
11250*x/100=7725
x= 68.7% discount
-40-2(3m+1/2)=7m-2 what does m equal
Answer: [tex]m[/tex] = −3
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
Step 1: Expand.
−40 − 6[tex]m[/tex] − 1 = 7[tex]m[/tex] − 2
Step 2: Simplify −40 − 6[tex]m[/tex] − 1 to −6[tex]m[/tex] − 41.
−6[tex]m[/tex] − 41 = 7[tex]m[/tex] − 2
Step 3: Add 6[tex]m[/tex] to both sides.
−41 = 7[tex]m[/tex] − 2 + 6[tex]m[/tex]
Step 4: Simplify 7[tex]m[/tex] − 2 + 6[tex]m[/tex] to 13[tex]m[/tex] − 2.
−41 = 13[tex]m[/tex] − 2
Step 5: Add 2 to both sides
−41 + 2 = 13[tex]m[/tex]
Step 6: Simplify −41 + 2 to −39.
−39 = 13[tex]m[/tex]
Step 7: Divide both sides by 13.
−[tex]\frac{39}{13}[/tex] = [tex]m[/tex]
Step 8: Simplify [tex]\frac{39}{13}[/tex] to 3.
−3 = m
Step 9: Switch sides.
[tex]m[/tex] = −3

If I had to take a guess, I'd say B.
Step-by-step explanation:
A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper level. The middle level has 40 more than twice as many seats as the upper level.
x + (2x + 40) + (3x – 50) = 15,002
The upper level has how many seats
Answer:
The equation x + (2 x + 40) + (3 x - 50) = 15,002 represents this scenario suitable.

The length of a football field including the end zones is 48 feet longer than four times the length of a tennis
court. It is also 282 feet longer than a tennis court.
How long is the foorball field?
How long is the tennis court?
Answer:
T=78 feet (Tennis court)
360 feet (Football Filed)
Step-by-step explanation:
4T+48 = T+282
The length of the football field is 360 feet.
The length of the tennis court is 78 feet.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The length of a football field including the end zones is 48 feet longer than four times the length of a tennis court.
And, It is also 282 feet longer than a tennis court.
Let the length of the tennis court = x
So, The length of the football field = 48 + 4x
Here, The length of the football field is 282 feet longer than a tennis court.
So, We get;
⇒ 48 + 4x = 282 + x
⇒ 4x - x = 282 - 48
⇒ 3x = 234
⇒ x = 78
Thus, The length of the football field = 48 + 4x
= 48 + 4×78
= 48 + 312
= 360 feet
The length of the tennis court = x
= 78 feet

which is the equation of a line that has a slope of 1/2 and passes through point (2,-3)
Answer:
y = (1/2)x - 4
Step-by-step explanation:
y = mx + b
y = (1/2)x + b
-3 = (1/2)(2) + b
-3 = 1 + b
b = -4
y = (1/2)x - 4
The area of a square garden is approximately 125 square feet. To the nearest foot, what is the length of the garden
Answer:
About 11 feet
Step-by-step explanation:
You have to find the [tex]\sqrt{125}[/tex], which is equal to 11.18033989. You round down to 11 feet.
In the garden, there were 15 red flowers, 5 blue flowers and 2 yellow flowers. What percent of the flowers were red?
Answer:
68.2
Hope this helps. :)
Answer:
I believe it would be 65?
Step-by-step explanation:
if if I divide 22 by 100 I will get 2.2.
And at 5 + 2 that means if you combine the blue flowers and yellow flowers you will get $7 in total.
And there's 15 red flowers 7 is kind 40 of 15 which is 100 because. 8+7=15 .
And for 15 to be completely split in half it would have to be 7.5.
But that's not how it works so if we put 8 & 7 into percents 8 would be 65 and 7 would be 35

Answer:
D. 1, 5, 7, 9, 11, 14, 16
Step-by-step explanation:
The following angles has the same measure as <3 = 20°:
m<7 = m<3 (corresponding angles are congruent)
m<5 = m<3 (alternate interior angles are congruent)
m<1 = m<3 (vertical angles are congruent)
m<14 = m<3 (corresponding angles are congruent)
m<16 = m<3 (alternate exterior angles are congruent)
m<9 = m<14 = m<3 (corresponding angles are congruent)
m<11 = m<9 = m<3 (vertical angles theorem and corresponding angles theorem)
Therefore, angles labelled D. 1, 5, 7, 9, 11, 14, and 16 all have the measure of 20°.

Given: AC = AB, CD = DE
m∠ABC = 70°, m∠ ECB = 35°
Prove: DE ║BC
m∠ACB = m∠______, By reason ( Base angles theorem, Exterior Angle theorem, Supplementary angles, Vertical Angles theorem ) - choose one
Answer:
a)[tex]\angle ACB = \angle ABC[/tex] By Base angle theorem
b)DE||BC since[tex]\angle DEC=\angle ECB[/tex] and they are alternate interior angles
Step-by-step explanation:
Given: AC = AB, CD = DE
∠ABC = 70°, m∠ ECB = 35°
Refer the attached figure
AB = AC
So, By Base angle theorem : if the sides of a triangle are congruent then the angles opposite these sides are congruent.
So, [tex]\angle ACB = \angle ABC[/tex]
So,[tex]\angle ACB = \angle ABC =70^{\circ[/tex] ----1
CD = DE
So, by Base theorem
[tex]\angle DCE = \angle DEC[/tex]
Let [tex]\angle DCE[/tex] be x
So,[tex]\angle DCE = \angle DEC[/tex]
[tex]\angle ACB= \angle DCE+\angle ECB = x+35[/tex]
Using 1
70 = x+35
35=x
[tex]\angle DCE = \angle DEC =35^{\circ}[/tex]
Now[tex]\angle DEC=\angle ECB=35^{\circ}[/tex]
So, DE||BC since[tex]\angle DEC=\angle ECB[/tex] and they are alternate interior angles

Answer:
y = -3x + 8
I've done the steps in the photo
Hope it helps (｡･ω･｡)
Answer:
y = - 3x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 16) and (x₂, y₂ ) = (1, 5)
m = [tex]\frac{5+16}{1-8}[/tex] = [tex]\frac{21}{-7}[/tex] = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 5 ) , then
5 = - 3 + c ⇒ c = 5 + 3 = 8
y = - 3x + 8 ← equation of line
