Suppose that Cecil, the tightrope walker, can only travel lengths of 5 feet, 6 feet, and 8 feet. He can travel forward or backward and can go farther than his ladder and come back. Show two number expressions that represent a way for Cecil to cross a tightrope of the following lengths. Make at least one of your expressions for each length include a backward movement.
