Question

choose all the expressions that are equivalent to -3r + 6s.
6r - 3s
6s - 3r
rs + rs + rs
r + r + r + 6s
6s - r - r - r

Explanation:

Step1: Recall commutative property

The commutative property of addition states that \(a + b=b + a\). So, \(-3r+6s = 6s-3r\).

Step2: Analyze \(6s - r - r - r\)

\(6s - r - r - r=6s-(r + r + r)=6s - 3r\).

Answer:

B. \(6s - 3r\), E. \(6s - r - r - r\)
