1. Is quadrilateral ABCD a rectangle? Why or why not?
2. Is quadrilateral WXYZ a rectangle? Why or why not?

Quadrilateral ABCD is a rectangle (more specifically a square)

Quadrilateral WXYZ is not a rectangle

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
