Efectuar el cuadrado de un binomio: ( x – 2y ) ^2 =Respuesta necesaria. Opción única.
(1 Punto)
x^2 – 4xy + 4y^2
x^2 + 4xy + y^2
x^2 – 4y^2
x^2 – 2xy + 4y^2
Answer:
La opción correcta es;
x² - 4·x·y + 4·y²
Step-by-step explanation:
La ecuación dada es (x - 2·y) ²
(x - 2·y) ² = (x - 2·y) × (x - 2·y) = x·x + x × (-2·y) + (-2·y) × x + (-2·Y) × (-2·y)
Lo que da;
(x - 2·y) ² = x² - x × 2·y - 2·y × x + (-2·y) ²
De lo que tenemos;
(x - 2·y) ² = x² - 2·y × x - 2·y × x + 4·y² = x² - 4·y × x + 4·y²
∴ (x - 2·y) ² = x² - 4·y × x + 4·y² = x² - 4·x · y + 4·y²
Y el resultado del cuadrado simplificado es (x - ·y) ² = x² - 4·y × x + 4·y² = x² - 4 · x · y + 4·y²
La opción correcta es (x - 2·y) ² = x² - 4·x · y + 4·y².

Find m+b and Write the equation
in Slope-Intercept form (y=mx+b)
Answer:
Slope: 3
y = 3x - 4
Step-by-step explanation:
Slope = rise/run = 3/1 = 3
y = mx + b
m = slope = 3
b = y-intercept = -4
y = 3x -4
Find two consecutive odd numbers such that seven times the smaller number is 17 more than six times the larger
Answer:
29 and 31
Step-by-step explanation:
Let
x = the first odd number
x + 2 = the second odd number
seven times the smaller number is 17 more than six times the larger
7*x = 17 + 6(x + 2)
7x = 17 + 6x + 12
Collect like terms
7x - 6x = 29
x = 29
x + 2 = 29 + 2
= 31
Check:
7*x = 17 + 6(x + 2)
7*29 = 17 + 6(29 + 2)
203 = 17 + 6(31)
203 = 17 + 186
203 = 203
Therefore, the two consecutive odd numbers are 29 and 31

Step-by-step explanation:
HELP ME PLEASEEEE
I only know how to do this in division, not multiplication
Answer:
360 × 30
= (360 × 3) × 10
= 1080 × 10
= 10800
Step-by-step explanation:
For the first two blanks, we will have to find a pair of factors of 30 that will make this the easiest to solve. Lets pair up all of the factors of 30.
1, 30
2, 15
3, 10
5, 6
So now we have found all of the factors of 30. We can eliminate 1 and 30, since we will just end up with 360 × 30 in the second line. We could use 2 and 15, but we will end up with _____ × 15 in the second line, which would be more difficult to solve for than the other two options. Now, you should use any one of the final two pairs of factors. I would use 3 and 10, since I find it much easier to multiply something by 3 and 10 than 5 and 6.
Lets put 3 in the first blank and 10 in the second blank. We will end up with:
(360 × 3) × 10
Now 360 × 3 would be 1080. So the second line would be:
1080 × 10
1080 × 10 would equal 10800. So the final line and the final blank would be:
10800
So in order, the lines would be:
= (360 × 3) × 10
= 1080 × 10
= 10800
I hope you find my answer and explanation to be helpful. Happy studying.
Which expression is equivalent to
-3/2 - 1/5
Answer:
- 17/10
Step-by-step explanation:
A restaurant has two different seating options: a table and a family booth. A table can seat 4 people, and a family booth can seat 10 people. The restaurant has a maximum capacity of 242 people. If the restaurant has 19 family booths, which inequality could be used to find t, the number of tables in the restaurant?
Answer: 242 = 190 + 4t
Step-by-step explanation:
You know that the maximum capacity of the restaurant is 242 people, meaning that at most there can only be that many customers seated at that time. Normally, the equation would be 242 = 10b + 4t, but since you already know the number of booths, your work is cut in half, giving you 242 = 10(19) + 4t. The equation would be this because you have the capacity being equal to the number of tables x the number of people at each table and the number of booths x the number of people seated at each of them.

The diagram below represents which percent?
An area model with 4 shaded sections and 1 unshaded section.
4%
45%
75%
80%
Answer:
80%
Step-by-step explanation:
There are 4 shaded sections and 1 unshaded section, so five sections in total.
4 sections are shaded, so the fraction would be 4/5.
Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
Answer:
D. 80%
Step-by-step explanation:
Well, the diagram shows 4/5ths knowing this is more than half we can auto matily mark out the first two A. and B. leaving C. 75% and D. 80% and D. is the best choice (sorry go too lazy to explain...)
Can anyone help with this?
Answer:
8
Step-by-step explanation:
In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.
Answer:
B. 8.0
Step-by-step explanation:
To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8
Solve for b.
ab +c=d
Answer: B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]
Step-by-step explanation:
you need to get B alone so that would be subtracting everything around it
ab = -c + d
then you need to get that a away from it by dividing both sides by A
B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Write the expression to represent the words.
Answer:
1. 7x
2. x+15
3. 18/x
Step-by-step explanation:
Assume the number is x because we don’t know what it is.
1. Product means multiplication so x * 7 equals 7x.
2. More means addition so x+15.
3. This one is easy. 18 divided by x = 18/x
Stacy wants to go on a vacation that will cost her at least $1540. She has $1825 saved but has
$65 deducted every week from her paycheck to pay for her insurance. At most, how many
weeks can she have these deductions made in order to afford her vacation
Answer:
4 weeks
Step-by-step explanation:
First,, we should subtract the vacation price from her savings to get the base. That is 1835-1540=295. Then we can do 295/65,, and then we get 4 7/13. So,, she can only afford 4 weeks of these deductions in order to have enough money for her vacation.

How much carpet would you need in square feet to cover a floor with dimensions of 12 feet by 15 feet?
Answer:8
Step-by-step explanation:
Area = Length x Width.
simple room measurement
Measure the length using the distance from one wall to the opposite wall.
Measure the width from wall to wall.
Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.
Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.
Repeat this process for each room.
NOT SURE HOW MU
Answer:
oi hi how are you
Step-by-step explanation:
12x + 8y = 24 Convert from standard form to slope-intercept form.
The required equation is y = -(3/2)x + 3 in slope-intercept form.
What is the standard form of linear equations?A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.
For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.
The equation is given in the question, as follows:
12x + 8y = 24
Isolate the variable of y for the above equation,
8y = - 12x + 24
Divided both sides by 8 into the equation,
y = - (12x)/8 + (24)/8
y = -(3/2)x + 3
This equation is in slope-intercept form.
