Final answer:
The equivalent expression is 25h + 12
Step-by-step explanation:
The given expression is 21h - 10h + 16 - 9 + 14h + 5.
To simplify, combine like terms. The like terms are the ones with the same variable, which in this case is 'h'.
Combining the 'h' terms, we have (21h - 10h + 14h). Simplifying this further, we get 25h.
Now, combining the constant terms, we have (16 - 9 + 5), which simplifies to 12.
Therefore, the equivalent expression is 25h + 12.
