Which statement best describes a square? a. a special rectangle that has four right angles b. a special trapezoid that has four sides of equal length c. a special rectangle that has four sides of equal length d. a special trapezoid that has four right angles

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

1. are the triangles similar and if so why? what is the value of x? show your work.
