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?

Reiny,
You don't list any "which of these ..."
However, the sum of any two sides must be greater than 3rd side ,
so ..
2x4 + 7x2
= 9x  6
So whichever is less than 9x6 could be a
third side
