To simplify the expression \((h + 12) + (p + 24)\), you combine the like terms:
- Combine \(h\) and \(p\) as they are the variables.
- Combine the constant terms \(12\) and \(24\).
So, the simplification looks like this:
\[ (h + 12) + (p + 24) = h + p + (12 + 24) = h + p + 36 \]
The simplified expression is h + p + 36.
Therefore, the correct response is:
h + p + 36.
