In parallelogram EFGH, EJ = 6x + 3 and JG = 10x - 5 What is EG?
A: 15
B: 12
C: 25
D: 30

Answer:
Step-by-step explanation:
It seems J is the intersection of diagonals.
We know diagonals of the parallelogram bisect each other.
It gives us:
Substitute and solve for x:
Find the value of EJ:
Find the value of EG:
Correct choice is D
Answer:
30
Step-by-step explanation:
We know that
Opposite sides of a parallelogram are equal. I am assuming J as the diagonal.
EJ = JG
=> 6x + 3 = 10x - 5
=> 6x - 10x = -5 - 3
=> -4x = -8
=> x = -8/-4
=> x = 2
Now,
EG = 2EJ
EG = 2(6 × 2 + 3)
EG = 2(12 + 5)
EG = 2(15)
EG = 30
