Answer:

Look below for answer! Have a great day and please mark me brainliest!

Step-by-step explanation:

Bedroom 1: 22x15=330

330x7.25=2392.5

Bedroom 2: 15x12=180

180x7.25=1305

Bedroom 3: 13x12=156

156x7.25=1131

2392.5+1305+1131= 4828.5

Bedroom 1: 22x15=330

330x6.75=2227.5

Bedroom 2: 15x12=180

180x6.75=1215

Bedroom 3: 13x12=156

156x6.75=1053

2227.5+1215+1053+100= 4595.5

Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.

If f(x)=-2x+7 and g(x)=x^2-2, what is [f o g](3)?<br><br> -7<br> -1<br> 1<br> 7

marusya05 [52]

Hello from MrBillDoesMath!

Answer: 21

Discussion:

g(3) = 3^2 -2 = 9 -2 = 7 =>

f(g(3)) = f ( 7) = 2(7) + 7 = 14 + 7 = 21

Thank you,

Simplify the expression 3x(x – 12x) + 3x2 – 2(x – 2)2. Which statements are true about the process and simplified product? Check

Kisachek [45]

<h3>1. The term $-2(x-2)^2$ is simplified by first squaring the expression (x – 2). </h3><h3>TRUE </h3><h3>2. The simplified product is a binomial. TRUE</h3><h3>3. After multiplying, the like terms are combined by adding and subtracting.</h3><h3>TRUE </h3><h3>4. The parentheses are eliminated through multiplication. TRUE</h3><h3>5. The final simplified product is $-28x^2 + 8x - 8$ FALSE</h3>

Step-by-step explanation:

Here, the given expression is :

$F(x) = 3x(x- 12x) + 3x^2-2(x-2)^2$

Now, let us first solve the given expression step wise:

$F(x) = 3x(x-12x) +3x^2 -2(x-2)^2\\= 3x(-11x) +3x^2 -2(x^2 +4 -4x)\\= -33x^2 + 3x^2 -2x^2 -8+8x\\= -32x^2 +8x - 8\\\implies F(x) = -32x^2 +8x - 8$

Now, here the given statements are:

1. The term $-2(x-2)^2$ is simplified by first squaring the expression (x – 2).

TRUE

2. The simplified product is a binomial. TRUE

3. After multiplying, the like terms are combined by adding and subtracting.

TRUE

4. The parentheses are eliminated through multiplication. TRUE

5. The final simplified product is $-28x^2 + 8x - 8$ FALSE

As the simplified expression is: $(-32x^2 +8x -8)$
