Hello :
answer : <span>C) x= -3 or x=5
because :
x=-3
2(-3)²-(-3)-15 = -3(-3+1)
18+3-15 =6
21-15 = 6....right
x=5
2(5)²-5-15 = 5(5+1)
50-20 =30
30=30.....right</span>

Suppose time Olive is traveling is x hours.
distance=speed×time
Olive's speed=30 miles per hour
time= x hours
Therefore, Olive's distance at time x will be given by:
distance=30×x= 30x
The right equation is:
Miles=30x
