Question

Quizplus · Accepted Answer

If one piece is z centimeters long, then the other piece will be the remaining length of the rope, which is (31 - z) centimeters. If one piece is z centimeters long, the other piece must be the remaining length of the rope. Therefore, the length of the other piece can be expressed as (31 - z)cm.
