D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1

Answer:
2(W + 6) + 2W = 90 where W = the width.
Step-by-step explanation:
The perimeter is 2L + 2W where L = the length and W = the width of the rectangle.
The length L = W + 6 so the equation is:
2(W + 6) + 2W = 90.
