<span>h = –16t 2 + 64t + 8
since both the launch height and target height are identical we can say height is 0
solve for t
0 = -16t^2 + 64t +8
-8(2t^2-8t-1) =0
divide both sides by -8
2t^2-8t -1 = 0
t = 4.12 and -0.121
since it can't be a negative number:
t = 4.12 seconds ( round off as needed)

<span>Simplifying
z + 18 = y
Reorder the terms:
18 + z = y
Solving
18 + z = y
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-18' to each side of the equation.
18 + -18 + z = -18 + y
Combine like terms: 18 + -18 = 0
0 + z = -18 + y
z = -18 + y
Simplifying
z = -18 + y</span>
