question
which expression is equivalent to \\(4\left(n - 3^2\
ight) + n\\)?

\\(3n - 6\\)
\\(3n - 9\\)
\\(5n - 36\\)
\\(5n - 144\\)

Explanation:

Evaluate the exponent inside the parentheses

$$ 3^2 = 9 $$

$$ 4(n - 3^2) + n = 4(n - 9) + n $$

Apply the distributive property

$$ 4(n - 9) + n = 4n - 36 + n $$

Combine like terms

$$ 4n + n - 36 = 5n - 36 $$

Answer:

• \(3n - 6\)
• \(3n - 9\)
• \(5n - 36\) (Correct answer)
• \(5n - 144\)
