The phrase “the product of a number and 7” indicates that you will multiply a variable (let's say \( n \)) by 7. The expressions that represent this correctly are those that involve multiplication between the variable and the number 7.
The correct variable expressions would be:
1. **7n** (this means \( 7 \times n \))
2. **n⋅7** (this also means \( n \times 7 \))
3. **n times 7** (this clearly states the multiplication of \( n \) by 7)
Thus, the correct answers from your list are:
- **7n**
- **n⋅7**
- **n times 7**
The other options (n7, n over 7, 7 over n, and 7 n) do not correctly represent the phrase “the product of a number and 7.”
