Which equation can be used to solve for x, the increase in
side length of the square in inches?

(A) Liability Coverage

Explanation:

After reading the question, I have no doubt it was Stephen fault for the collision. So, even if the question doesn't say, you can conclude he will be found "at-fault" which means he will have to pay for fixing Keisha's car. In this case, he will have to pay for replacing Keisha's bumper. If he has a liability coverage, the insurance will pay for this, because the liability coverage means that any liability (crash, coallision or whatever) that is your fault and caused damage to others (like in their cars or other property or if they suffer body injuries) will be paid by the insurance.
