Which best explains if quadrilateral WXYZ can be a parallelogram? β© WXYZ can be a parallelogram with one pair of sides x+2 mm 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.
