Answer:
x^2 - 3x - 40
Step-by-step explanation:
x = 8 and x = -5
x - 8 = 0 and x + 5 = 0
(x - 8)(x + 5)
x^2 + 5x - 8x - 40
x^2 - 3x - 40
Answer: x^2 - 3x - 40

Answer:
b = 12.6
Step-by-step explanation:
a*2 + b*2 = c*2
6*2 + b*2 = 14*2
36 + b*2 = 196
Subtract 36 from both sides
36 + b*2 = 196
-36 -36
b*2 = 160
Find the square root of both
b = 12.64911064 or 12.6
B. 45 feet/second
To find out how fast it can go in 1 second, we divide it by 2
