Its D(5,-4) XD ;p
because I did it and got it right but don't take my word for it just ask the other suggestions <span />
Ok first we can split it in two :

and

.
The derivative of

is 3.
For the first part, we use the chain rule :
![[f(g(x))]'=g'(x)f'(g(x))](https://tex.z-dn.net/?f=%5Bf%28g%28x%29%29%5D%27%3Dg%27%28x%29f%27%28g%28x%29%29)
hence

(since the derivative of the exponential is itself) hence
Answer:
25ft
Step-by-step explanation:
12 inches = 1 ft. Hence,
120 inches = 10 ft.
Likewise,
1 yard = 3 ft
5 yards = 15 ft
Hence, the length of both cars together is,
10 ft + 15 ft = 25 ft
