Ms. Sue,
Please show us how you think these problems should be solved  or where you're stuck. Do not post any more problems until you've shown us some effort on these other 10 or so problems.

7(3x^31)= 21x^2
7(2x^21)= 14x
so would it be 21x^2+14x/x
I don't know how to go further than this

Reiny,
I don't know the foggiest idea what you are doing.
first of all, I think you probably meant
f(x) = (7x^3 + 7x^2)/x , or else the last term would simply be 7x
from my assumption, then
f(x) = 7x^2 + 7x
f'(x) = 14x + 7
