Answer: JG= 12.
Explantation: Since it is a parallelogram, we know that EJ and JG are congruent (equal). Therefore, we set EJ and JG as an inequality. (3w = w + 8) We solve for W and get w=4. Plug in 4 into the JG equation (4 + 8). The answer would be 12.

The midpoint of the line having the endpoints

and

is

basically average them
so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2
so the midpoint can be found by doing



the midpoint is
