Four expressions are shown below:

4(8x + 2)
4(7x + 3)
32x + 8
28x + 12

which two expressions are equivalent to 4(7x + 2 + x)?
1. a and b
2. b and c
3.a and d
4. a and c

The correct answer is number 4.

Step-by-step explanation: First, solve the (). 7x + x or 7x + 1x = 8x. Now, you have 4(8x + 2). That would be the first choice, A. But what about the second one? Well, 4 x 8x would be 32x, and 4 x 2 would be 8. Now put that together. 32x + 8. Is there an expression like that? Yes, there is. Choice C. Now that means choice A and C are equivalent to 4(7x + 2 + x). Only number 4 holds those choices, so your answer would be number 4. Hope this helped! :)

answer: was that a question or answer?

step-by-step explanation:

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.
