4-82.

Use an algebraic expression to represent each sequence of lengths shown below. Homework Help ✎

Think of this as being a tightrope for Croakie to cross. How would you describe his path using this picture?

*x*+ 1 or*x*+ 1 +*x*This problem is very similar to part (a).

If the lengths labeled ''*m*'' were instead labeled as ''*x*'', how would you write the expression?3

*m*+ 5 or*m*+*m*+*m*+ 5Use parts (a) and (b) as guides if you are having trouble. Remember that the variable represents a number, so you can use it in an expression just as you would a number.
