Question

Suppose RS is congruent to MN. For the set of lenghts solve for x and find the lenght of the segment.
RS=3x+17, MN= 7x-15.

x=
RS=
MN=

Answer 1

         RS ≡ MN
  3x + 17 = 7x - 15
- 3x          - 3x
          17 = 4x - 15
       + 15        + 15
          32 = 4x
           4      4
            8 = w
