Iam having trouble with a math problem it's -5+9(-6+7 (4-4)

Which of the following would represent the sum of 3 consecutive integers if x is the first integer?

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]
