Answer 1

[AI-generated answer — Bot GPT-4o]

To evaluate the expression \( n \cdot 3 - 3n + 12 \) when \( n = 4 \), follow these steps:

1. Substitute \( n = 4 \) into the expression:

\[ 4 \cdot 3 - 3 \cdot 4 + 12 \]

2. Perform the multiplications:

\[ 12 - 12 + 12 \]

3. Perform the addition and subtraction from left to right:

\[ 12 - 12 = 0 \]
\[ 0 + 12 = 12 \]

Therefore, the value of the expression when \( n = 4 \) is:

\[
12
\]
