Question

Rewrite the following phrase as a mathematical expression: twice a number increased by eighteen.18 n + 22 n + 182 + 182(18 n)

Answer 1

Let set n for the missing number.

Hence, if we have "twice a number" we can write it as 2n.

Then, if it increased by eighteen. We need to add up to 18 to the before expression.

Therefore, the whole result expression is 2n +18.
