Each of the diagrams below represents tightrope moves for an acrobat. For each diagram:

Describe what the diagram shows about the routine and the length of the tightrope.

Figure out the length of the acrobat’s trick.

This is similar to writing an expression for an acrobat's routine. Think of the tricks as being numerical lengths of the rope.

First, describe the routine based on the diagram.

The acrobat performs a trick three times and then walks

feet to get to the end of the foot tight rope. Next, determine how far each trick travels. Looking at the tightropes, the

's match up withfeet. Since unknown, but equal, lengths combine to make feet, you know that each length is feet. The trick travels

feet. Follow the same steps as in part (a).
