Question

1. -4x - 10x

Explanation:

Step1: Combine like terms

To combine \(-4x\) and \(-10x\), we add their coefficients. The coefficient of \(-4x\) is \(-4\) and the coefficient of \(-10x\) is \(-10\). So we calculate \(-4 + (-10)\).
\(-4 + (-10) = -14\)
Then we multiply this sum by \(x\), so we get \(-14x\).

Answer:

\(-14x\)
