The rhombus has four equal sides ⇒ JK=ML=KL
4x-8 = x+13
4x - x = 13 + 8
3x = 21
x = 7
ML = x+13 = 7 + 13 = 20
KL=ML ⇒
6y+2 = 20
6y = 20-2
6y = 18
y = 18/6
y = 3
The correct answer is d=45 :)
Answer:
(3,2)
Step-by-step explanation:
I changed the first equation to x=y+1. Then I substituted the x in the second equation with y+1. So, I got 4(y+1)-3y=6. Then 4y+4-3y=6 turns into y=2. Then you replace y with 2 in the first equation. -x+2=-1. -x=-3 or x=3.
