4-123.
  1. . Use the values given below for the lengths in the diagrams from problem 4-122 to find the total length of each segment. For example, if x were equal to 3 units in part (a) of problem 4-122, the line segment would be 3 + 1 + 3 = 7 units long. Homework Help ✎

    1. Part (a) using x = 4one-half

    2. Part (b) using m = 4

    3. Part (c) using y = 5.5

Remember that the expression for part (a) is x + 1 + x.
If you put in the value for x and simplified the expression, what answer would you get?
Try the problem on your own before checking the answer.

Look back at part (b) of 4-122. Using the expression you wrote, substitute 4 for ''m'' and simplify the expression.

This problem is very similar to parts (a) and (b). If you are having trouble, refer to those problems.
