b (12,7)
c (-8,8)
d (-3,-4)

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

5x + 2 = 12 solve the following equation. then place the correct number in the box provided.
