Can you please check my answers?

For the given functions f and g, find the indicated composition.

5. f(x)=7x+9, g(x)=2x-1

I got 14x+2

For the given functions f and g, find the indicated composition.

8. f(x)=-5x+3, g(x)=6x+3

I got -30x+18

Find functions f and g so that h(x)= (f *g)(x)

12. h(x)= 1/(x^2-2)

I got (f)=1/x, g(x)=x^2-2

14. h(x)=(-2x+19)^5

I got f(x)x^5, g(x)=-2x+19
