Question

18h + 6(2 + h) - 7 =

Explanation:

Step1: Expand the parentheses

Using the distributive property \(a(b + c)=ab+ac\), we expand \(6(2 + h)\) to get \(6\times2+6\times h = 12 + 6h\). So the expression becomes \(18h+12 + 6h-7\).

Step2: Combine like terms

First, combine the \(h\)-terms: \(18h+6h=(18 + 6)h = 24h\). Then combine the constant terms: \(12-7 = 5\). So the simplified expression is \(24h + 5\).

Answer:

\(24h + 5\)
