By doing some calculation, 2+3=18, 3+5=42, 6+2=48 and find 5+6=??  Choose the correct choice from the following choices.
A) 74
B) 70
C) 72
D) 76
E) 78
Given 2+3=18==&gt; (2^2+3^2)+(2+3)=18   3+5=42==&gt; (3^2+5^2)+(3+5)=42   6+2=48==&gt; (6^2+2^2)+(6+2)=48   So 5+6=72==&gt; (5^2+6^2)+(5+6)=72   ANSWER:72
<result>C</result>
