a ladder is resting against a wall. the top of the ladder touches the wall at a height of 12 feet. Find the distance from the wall to the bottom of the ladder if the length of the ladder is 12feet less than twice its distance from the wall.
x^2 + 12^2 = (2x-12)^2
That is a start. I am not going to do it for you. It is too much like the last one I did for you.
