4-83.

In parts (a) through (c) below, refer to the previous problem. You will find the length of the line segments in problem 4-82 by substituting given values for the variables. For example, if x is 3 units in part (a) of problem 4-82, the line segment would be 3 + 1 + 3 = 7 units long. Homework Help ✎

  1. Find the length of the line segment in part (a) of problem 4-82 using x = 4.

  2. Find the length of the line segment in part (b) of problem 4-82 using m = 4.

    After substituting 4 for m, the expression for the length of the line segment is 4 + 4 + 4 + 5.

  3. Find the length of the line segment in part (c) of problem 4-82 using y = 5.5.

  • Your new expression will look like 5.5 + 2 + 5.5 + 2. Find the value of this expression to determine the
    length of the line segment.
