what is the height of the trapezoid?

cm

Need ! give step by step solutions on how to solve number one \frac{9-2\sqrt{3} }{12+\sqrt{3} } number two x+4=\sqrt{13x-20} number three (domain and range) f(x)=2\sqrt[3]{x} +1

A50% increase followed by 33 1/2% decrease

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
