Finding side lengths of a 30 60 90 triangle

Given the median qr and trapezoid mnpo what is the value of x?

Interpret the following expression (5y^2-7)^3/(2y)^2

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
