Question

9 2(x + 2) + x

Explanation:

Step1: Expand the bracket

Using the distributive property \(a(b + c)=ab+ac\), we have \(2(x + 2)=2\times x+2\times2 = 2x + 4\)

Step2: Combine like terms

Now we have the expression \(2x + 4+x\). Combine the \(x\) terms: \(2x+x=3x\), so the simplified expression is \(3x + 4\)

Answer:

\(3x + 4\)
