3x/5.. because when the bracket opens then the -7 and +7 get cancelled..
Vertical angles are congruent due to the fact that they intersect. If they did not, they would in fact be parallel. (last section)
I agree with the 14x all right, but the remainder of the other part is 178. I'm going to recheck my answer. I'm not confident about using synthetic division for this question. It is 57 years since I did something like this. If I was more confident, I would list the results of synthetic division because it is much easier to show than long division. I'm saying the answer should be 14x + 178.
