# 9 squared plus a number equals 110?

Feb 20, 2018

The unknown number is $29$.

#### Explanation:

First, you find out what $9$ squared equals, which is $81$. Then, you would subtract $81$ from $110$ and it would give you $29$.

${9}^{2} + n = 110$

$81 + n = 110$

$n = - 81 + 110$

$n = 29$

Hope this helps!
