I got you , x= -24 , try this tell me if it works
The formula for the area of a trapezoid is A=1/2(base one+base two)h
All you have to do is find the base one, base two, and height using the given information and then plug it into the equation.
Rolling an even number would be 1/2 possibility while flipping tails would be 1/2 possibility hence the answer is 1/4
Concurrent . Point of concurrency
I took a picture of the work instead ^^
