Answers:
- JK = 29
- LM = 29
- KL = 10
- MJ = 10
- JK = LM and KL = MJ
========================================================
Step-by-step 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.
