Question

simplify: n + n + n; 2n; 4n; 3n; 0n

Explanation:

Step1: Identify like terms

The expression is \( n + n + n \). All terms are like terms (same variable \( n \)).

Step2: Combine like terms

When adding like terms, we add their coefficients. The coefficient of each \( n \) is 1 (since \( n = 1 \times n \)). So, \( 1n + 1n + 1n=(1 + 1 + 1)n \).

Step3: Calculate the sum of coefficients

\( 1+1 + 1 = 3 \), so the simplified form is \( 3n \).

Answer:

C. \( 3n \) (assuming the third option is labeled C, with text \( 3n \))
