Question

write an equivalent expression by distributing the \-\ sign outside the parentheses: -(-8r - 9.8s) + 8.1

Explanation:

Step1: Distribute the negative sign

When we distribute the negative sign outside the parentheses \(-(-8r - 9.8s)\), we multiply each term inside the parentheses by \(-1\). So, \(-1\times(-8r)=8r\) and \(-1\times(-9.8s) = 9.8s\).

Step2: Combine with the remaining term

After distributing, we have \(8r + 9.8s+8.1\) since the remaining term is \(+8.1\) which we just add to the distributed terms.

Answer:

\(8r + 9.8s + 8.1\)
