Help quick

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

What is 20+(5 x 2/5 )+ 3 show your work

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