The quotient of 2 times some number and four.
Hope this helps and sorry if it is wrong but it’s what I got
It's a equilateral triangle with each side being equal to the radius.
So the area is
-5y + 8 = -3y + 10
We need to get y on one side.
Add 3y to both sides.
-2y + 8 = 10
We need to get 2y by itself.
Subtract 8 from both sides.
-2y = 2
Divide both sides by -2 to solve for y.
y = -1
I hope this helps!
