Two sides of a triangle measure 2x – 4 and 7x – 2 units, respectively. Which of these is a possible length for the third side of the triangle? 
---
Let the 3rd side meansure M
M< (2x-4)+(7x-2) = 9x-6
M> (7x-2)-(2x-4) = 5x+2
---------------------------
5x+2 < M < 9x-6
------
A)
3x units
Not in the interval
---
B)
6x units
In the interval.
------
C)
5x + 2 units
Not in the interval.
