please check my answers and help me with the last one please, I cant get it to come out right.

Divide using long division or synthetic division.

2.(x^2 + 13x + 40)/ (x + 5)

I got x + 8

5. 3m^3+7m^2-16m+16/ m+4

i got 3m^2-5m+4

7.(21x^3 - 7)/(3x - 1)(this one I cant get the anwswer to match up with my answer choices.)

- Long and synthetic division -

all right, on 7), the answer is obvious, as the numerator (with 7 factored out) is a difference of two cubes, one factor dividing out the denominator. So you can't do that, I know, but I dont know how I can help you as I can't do division here. I did it on paper, and I get the right answer.
