t = 4 seconds
Step-by-step explanation:
The height of a soccer ball as a function of time is given by :

We need to find the time when the ball hit the ground i.e. h = 0
Put h = 0 in above equation. So,

It is a quadratic equation such that,
t = -1 s and t = 4 s
Neglecting -1 s, the ball will hit the ground after 4 seconds.
The distributive property: a( b + c) = ab + ac
3(x + 2) = 3x + 3 · 2 = 3x + 6
