Question

1. 5(x - 4) + 2

Explanation:

Step1: Apply distributive property

We use the distributive property \(a(b - c)=ab - ac\) to expand \(5(x - 4)\). So \(5(x - 4)=5\times x-5\times4 = 5x-20\).
The expression becomes \(5x - 20+2\).

Step2: Combine like terms

We combine the constant terms \(-20\) and \(2\). \(-20 + 2=-18\).
So the simplified expression is \(5x-18\).

Answer:

\(5x - 18\)
