The door is on the front of Building #3. The door is 1 foot off the ground.
The ramp can be no shorter than 2 feet and no longer than 10 feet

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]

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)
