Answer:

9(x+3) + 2(x+3) or 10(x+2) +(x+5)

Step-by-step explanation:

First you want to distribute the equation.

4(x+1) + 7(x+3) multiplied out is

4x + 4 + 7x + 21

Now we add like terms so it comes out to

11x + 25

Two expressions that can come out to equal 11x + 25 is. 9(x+3) + 2(x+3) or 10(x+2) +(x+5)

Answer:

C

15 + x

Step by step explanation

For Company X, the initial cost is 30 cents  plus 5 cents per minute, so the expression would be 30 + 5x (x would represent minutes.

For Company Y, the initial cost is 15 cents  plus 4 cents per minute, so the expression would be 15 + 4x (x would represent minutes.)

Then subtract the expression of Y from the expression of X to show the difference in value between Y and X.

So, 30 + 5x - (15 +4x)

Distribute the subtraction sign.

30 + 5x - 15 - 4x

Solve across.

15 + x
