Answer:
   A.  7 seconds
Step-by-step explanation:
We assume your factored equation is something like ...
   h(t) = -16t(t -7)(t +2)
The time it takes the ball to reach the ground is the positive value of t that makes a factor zero:
   t -7 = 0   ⇒   t = 7
The ball will land on the ground in 7 seconds.

Answer:
x = 40
Step-by-step explanation:
The ADF is 90 degrees so the CAF will also be 90
So you do
( x + 15 ) + 90 + 35 = 180
x + 15 + 90 + 35 - 90 = 180 -90
x + 15 + 35 = 90
x + 15 + 35 - 35 = 90 - 35
x + 15 = 55
x + 15 - 15 = 55 - 15
x = 40
 
        
             
        
        
        
Answer:
29 and 35
Step-by-step explanation:
x+y=64
x-y=6
Solve by substitution. 
x=6+y
6+y+y=64
6+2y=64
y=29
Then plug in 29 for y. 
x+29=64 ......35
