Thanks everybody, I got a solution for figuring out the answer (which is 36) to my first question. But I still need help with the other ones below. Any help would be appreciated:
2. What are the solutions of the equation x2 + 4x = 96? (1 point) 2, –48
–12, 8
–2, 48
12, –8
3. What are the solutions of the equation x2 + 14x = –130? (1 point)2, –16
10, –13
–2, 16
no solution
4. A rocket is launched from atop a 105-foot cliff with an initial velocity of 156 ft/s. The height of the rocket above the ground at time t is given by h = –16t2 + 156t + 105. When will the rocket hit the ground after it is launched? Round to the nearest tenth of a second. (1 point)4.9 s
9.8 s
0.6 s
