Two pyramids like the one below sit on top of the gate at the entrance to the bridge. Which expression shows how to determine the minimum amount of some use to make each of the pyramids?

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]

At which value in the domain does f(x) =0?

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
