Ineed you to match column a to the simplified version in column b

After two years, how much has been paid into interest?

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]

Given: m zade = 60° and m2cdf = (3x + 15) prove: x = 15
