Answer:
excuss me where the picture
Step-by-step explanation:
I believe it is the final choice because it correctly compares 2 sets of corresponding sides.
We will use the FOIL method to solve this.
(7x-7)(x+1)
Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

Now, we need to simplify by combining like terms.

If you look, -7x and 7x are gone. This is because they cancel each other out.
I hope this helped and maybe consider giving me brainliest :)
