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.

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
