Question

Quadrilateral WXZY is a square. If YX = 30 and WT = 2x – 7, then find the value of x.

Answer 1

Whatever WT equates to, it must be the same as YX, because it is a quadrilateral. Simply, you plug in for x until you find a number that works.

Answer 2

In this case, x will have to be a decimal, because any number multiplied by an even number will always equal an even number.

Answer 3

X=18.5
