Answer:
10 years
Step-by-step explanation:
let they become of same height after t years
3ft=36 inches
hence
height of A
Ha=36+21t
8ft=96 inches
height of B
Hb = 96+15t
as Ha =Hb
36+21t =96+15t
21t-15t =96-36
6t=60
t=60/6
t= 10 years
Answer: It'll take 11 years for them to be the same height at 20 feet and 6 inches.

h(4) = 2^4 = 16
the answer is y, I just took the test
