2,5
Step-by-step explanation:
Answer:
4 sec
Step-by-step explanation:
let y = 0 which is the height when the rocket hits the ground
-3t^2 + 6t + 24 = 0
-3(t^2 - 2t - 8) = 0
-3(t - 4)(t + 2) = 0
t = 4 or t = -2
time cannot be negative, so t = 4 sec
3+5(x-4)
= 3 + 5x - 20
= 5x - 17
3(x-6) = -12
3x - 18 = -12
3x = 6
x = 2
