You take 94.5 and divide by 4.5 get 21
You have to factor this...
So you have started with this...
x²-x-2=0
If you factor this you will get
(x+1)(x-2)=0
This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!

Answer:
16
Step-by-step explanation:
The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
