Answer

12 Explanation 1. Substitute the value of n Replace n with 4 in the expression n^2 - 3n + 8. 2. Calculate n^2 Compute 4^2 = 16. 3. Calculate -3n Compute -3 \times 4 = -12. 4. Add the results Add 16, -12, and 8: 16 - 12 + 8.

Explanation

1. Substitute the value of $n$<br /> Replace $n$ with 4 in the expression $n^2 - 3n + 8$.<br />2. Calculate $n^2$<br /> Compute $4^2 = 16$.<br />3. Calculate $-3n$<br /> Compute $-3 \times 4 = -12$.<br />4. Add the results<br /> Add $16$, $-12$, and $8$: $16 - 12 + 8$.
