Let's match the verbal phrases in Column A to the corresponding mathematical expressions in Column B:

1. **The sum of twice a number and 5**  
   - **Verbal phrase**: "Twice a number" means \(2n\), and "the sum of that and 5" means \(2n + 5\).
   - **Mathematical expression**: **C. \(2n + 5\)**

2. **The difference between a number and 7**  
   - **Verbal phrase**: "The difference between a number and 7" means \(n - 7\).
   - **Mathematical expression**: **A. \(n - 7\)**

3. **Three times a number decreased by 4**  
   - **Verbal phrase**: "Three times a number" means \(3n\), and "decreased by 4" means \(3n - 4\).
   - **Mathematical expression**: **J. \(3n - 4\)**

4. **The quotient of a number and 5**  
   - **Verbal phrase**: "The quotient of a number and 5" means \(n \div 5\) or \(\frac{n}{5}\).
   - **Mathematical expression**: **H. \(\frac{n}{5}\)**

5. **The square of a number**  
   - **Verbal phrase**: "The square of a number" means \(n^2\).
   - **Mathematical expression**: **E. \(n^2\)**

6. **The product of 7 and the sum of a number and 2**  
   - **Verbal phrase**: "The sum of a number and 2" means \(n + 2\), and "the product of 7 and that sum" means \(7(n + 2)\).
   - **Mathematical expression**: **G. \(7(n + 2)\)**

7. **Half of a number increased by 10**  
   - **Verbal phrase**: "Half of a number" means \(\frac{n}{2}\) or \((1/2)n\), and "increased by 10" means \(\frac{n}{2} + 10\).
   - **Mathematical expression**: **F. \((1/2)n + 10\)**

8. **The difference between 9 and three times a number**  
   - **Verbal phrase**: "Three times a number" means \(3n\), and "the difference between 9 and that" means \(9 - 3n\).
   - **Mathematical expression**: **B. \(9 - 3n\)**

9. **Five more than the square of a number**  
   - **Verbal phrase**: "The square of a number" means \(n^2\), and "five more than that" means \(n^2 + 5\).
   - **Mathematical expression**: **I. \(n^2 + 5\)**

10. **Four times the sum of a number and 3**  
   - **Verbal phrase**: "The sum of a number and 3" means \(n + 3\), and "four times that sum" means \(4(n + 3)\).
   - **Mathematical expression**: **D. \(4(n + 3)\)**

### Final Matching:

1. C. \(2n + 5\)
2. A. \(n - 7\)
3. J. \(3n - 4\)
4. H. \(\frac{n}{5}\)
5. E. \(n^2\)
6. G. \(7(n + 2)\)
7. F. \((1/2)n + 10\)
8. B. \(9 - 3n\)
9. I. \(n^2 + 5\)
10. D. \(4(n + 3)\)
