Answers:
- JK = 29
- LM = 29
- KL = 10
- MJ = 10
- JK = LM and KL = MJ
========================================================
Explanation:
Let's plug in the given x value
- JK = 5x+9 = 5*4+9 = 20+9 = 29
- LM = 6x+5 = 6*4+5 = 24+5 = 29
Both JK and LM are equal to 29, so this means JK = ML
Now use the y value
- KL = 2y-6 = 2*8-6 = 16-6 = 10
- MJ = y+2 = 8+2 = 10
Both JM and KL are equal to 10, so JM = KL
These facts are sufficient to prove we have a parallelogram.
The correct value is -10.
7 plus negative 10 equals negative 3.
Negative 3 times 4 equals -12.
Or, (7+-10=-3•4=-12)
8^2 + x^2 = 10^2
64 + x^2 = 100
x^2 = 36
x = 6
