Question

1. -v + 12v

Explanation:

Step1: Combine like terms

We have \(-v + 12v\). The coefficient of \(v\) in the first term is \(-1\) and in the second term is \(12\). To combine like terms, we add the coefficients: \((-1 + 12)v\).

Step2: Calculate the sum of coefficients

\(-1 + 12 = 11\), so \((-1 + 12)v = 11v\).

Answer:

\(11v\)
