Score: \( 4 / 5 \) Penalty: none Question Write an equivalent expression by distributing the " - " sign outside the parentheses: \[ -(3.4 n+5 p-7.5) \]

To distribute the negative sign, you’ll need to multiply each term inside the parentheses by -1. This means you change the sign of each term. So, for your expression: \[ -(3.4 n + 5 p - 7.5) \] becomes \[ -3.4 n - 5 p + 7.5. \] Thus, the equivalent expression is: \[ -3.4 n - 5 p + 7.5. \]
