Answer:
11x+7
Step-by-step explanation:
This is because, in order to simplify, first you need to distribute the 2 into the x+5. So, you get 2x+10. Then you get 9x-3+2x+10. The 9x and 2x combine to get 11x. The -3+10 combine to get 7. So you have 11x+7.
<span>h = 0 when it hits the ground, therefore:
-16t^2 + 48t = 0
--------------------------------------...

-16t(t + 3) = 0
:
Two solutions
t = 0, when it begins it's upward journey
and
t = 3 sec, when it returns to earth
