Question

1. (4x + 8) + (7x + 3) =

Explanation:

Step1: Remove parentheses

Since there are no operations outside the parentheses that affect the terms inside (just addition), we can remove the parentheses: \(4x + 8 + 7x + 3\)

Step2: Combine like terms

For the \(x\)-terms: \(4x + 7x = 11x\)
For the constant terms: \(8 + 3 = 11\)
So combining these, we get \(11x + 11\)

Answer:

\(11x + 11\)
