7x+8 is the equivalent equation
Acceleration = (v1-v0)/t = (30-50)/5=-20 mph/s
Additional time it takes to stop
=(0-30)/-20
=1.5 seconds
Total time = 5+1.5 =6.5 seconds.
Basically add up the given side lengths and subtract that from 180 for the triangles
The answer is 10,000
25,000 - 15,000 = 10,000
