Final answer:
To add the given expressions, combine like terms. The result is 10m + 8.
Step-by-step explanation:
To add the given expressions, we combine like terms. We add the coefficients of the m terms and add the constants separately. So, (8m + 3) + (2m + 5) becomes 8m + 2m + 3 + 5. Simplifying further, we get 10m + 8.
