I'd have to say it's A. Please don't blame me if I'm wrong. :)
Using Isosceles triangle theorem we can determine that JI = JK
Thus
5x + 4 = 2x+7
3x = 3
x=1
Plug it back into the eqution for JK
2(1) + 7 = JK
9 = JK
Answer:
i got -45, so make sure you wrote the problem right because i solved correctly.
Answer:
answer would be -10 for x
5x^2y is the answer which leaves you with 3y^2 and -4xz
