The sum of eleven times a number n and twice the number

Answer 1

11n + 2n; 13n

Explanation:

1. The expression

n = a number

11n = 11 times the number

2n = twice the number

11n + 2n = the sum of the two values

The expression is 11n + 2n.

2. The simplified expression

`\begin{array}{rcl}11n + 2n & = & (11 + 2)n\\ & = & \mathbf{13n}\\\end{array}`

The simplified expression is 13n.
