Question

Write an equivalent expression by distributing the '-' sign outside the parentheses: -(3u - 8.2)?

1) -3u + 8.2
2) -3u - 8.2
3) 3u + 8.2
4) 3u - 8.2

Answer 1

To find the equivalent expression by distributing the negative sign in -(3u - 8.2), multiply each term inside the parentheses by the negative sign. This results in the expression -3u + 8.2.

Step-by-step explanation:

To write an equivalent expression by distributing the '-' sign outside the parentheses for the expression -(3u - 8.2), we need to apply the rule that tells us to change the sign of each term inside the parentheses when we distribute the negative sign. Here's how it works step-by-step:

• Take the first term inside the parentheses (3u) and multiply it by the negative sign to get -3u.
• Take the second term inside the parentheses (-8.2) and again multiply it by the negative sign to get +8.2.

After distribution, we have -3u + 8.2. Hence, the answer is option (1) -3u + 8.2.
