1. **State the problem:** Simplify the expression $6(x + 3) - 10 + 2x$ and find which of the given options matches the result. 2. **Use the distributive property:** Multiply $6$ by each term inside the parentheses. $$6(x + 3) = 6 \times x + 6 \times 3 = 6x + 18$$ 3. **Rewrite the expression:** $$6x + 18 - 10 + 2x$$ 4. **Combine like terms:** Combine the $x$ terms and the constant terms separately. $$6x + 2x + 18 - 10 = (6x + 2x) + (18 - 10)$$ 5. **Simplify:** $$8x + 8$$ 6. **Conclusion:** The simplified expression is $8x + 8$, which corresponds to option A.
