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

The rectangle on the right is the image of the rectangle on the left. what transformation would result in this image? reflection rotation translation dilation

Evaluate the expression. (9 + 5)(3 + 2)0
