Question

Quizplus · Accepted Answer

The correct operation involves adding the coefficients of like terms, which are the terms with $\sqrt{6}$. So, $9\sqrt{6} + 2\sqrt{6} + 9\sqrt{6} = 20\sqrt{6}$. The +20 remains unchanged because it does not have a like term to combine with. Therefore, the answer is $20\sqrt{6} + 20$.
