Question

add.
$(p + 7) + (p + 2)$

Explanation:

Step1: Remove parentheses

We have \((p + 7) + (p + 2)\), removing the parentheses gives \(p + 7 + p + 2\).

Step2: Combine like terms

Combine the \(p\) terms: \(p + p = 2p\), and combine the constant terms: \(7 + 2 = 9\). So we get \(2p + 9\).

Answer:

\(2p + 9\)
