1. The problem is to identify the degree and the number of terms of degree 3 in the polynomial $n + 7n^3 - 3$. 2. The degree of a polynomial is the highest power of the variable in the polynomial. 3. The polynomial is $n + 7n^3 - 3$. 4. The terms are: - $n$ (degree 1), - $7n^3$ (degree 3), - $-3$ (degree 0). 5. The highest degree term is $7n^3$, so the degree of the polynomial is 3. 6. The number of terms with degree 3 is 1 (only $7n^3$). 7. Therefore, the degree is 3 and the number of degree 3 terms is 1. Final answer: Degree = 3, Degree 3 terms = 1.
