Question

1. 5n + 11n

Explanation:

Step1: Identify like terms

The terms \(5n\) and \(11n\) are like terms (both have the variable \(n\)).

Step2: Combine like terms

To combine like terms, we add their coefficients. The coefficient of \(5n\) is \(5\) and the coefficient of \(11n\) is \(11\). So, \(5 + 11 = 16\). Thus, \(5n+11n=(5 + 11)n = 16n\).

Answer:

\(16n\)
