Quadrilateral W X Y Z is shown. The length of W X is (x + 8) millimeters, the length of X Y is (2 x minus 5) millimeters, the length of Z Y is 15 millimeters, and the length of W Z is (x + 2) millimeters. Which best explains if quadrilateral WXYZ can be a parallelogram? WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm. WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 7 mm. WXYZ cannot be a parallelogram because there are three different values for x when each expression is set equal to 15. WXYZ cannot be a parallelogram because the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.
