Answer: The formula to find the speed of the Ford could be F = B - 20.
Since the Ford is 20 mph slower than the Buick, all you have to do is subtract 20 from the speed of the Buick. We know the speed of the Buick, it is 65.
Therefore, the speed of the Buick is 65 - 20 or 45 mph.

(goh)=g(h(x))
h(0)=0^2+4=4
g(4)=8
(goh)(0)=8
