Which pair of expressions below are equivalent? r+r+r+r+s and 5rs 4(8r) and 12 r 4r+8s and 8s+4r 9r+9r and 81 r

Compare Expressions: Compare the first pair of expressions. The first expression is r+r+r+r+s, which simplifies to 4r+s. The second expression is 5rs. These two expressions are not equivalent because 4r+s does not equal 5rs.Compare Expressions: Compare the second pair of expressions. The first expression is 4(8r), which simplifies to 32r. The second expression is 12r. These two expressions are not equivalent because 32r does not equal 12r.Equivalent Expressions: Compare the third pair of expressions. The first expression is 4r+8s. The second expression is 8s+4r. These two expressions are equivalent because addition is commutative, meaning that the order of the terms does not matter.Compare Expressions: Compare the fourth pair of expressions. The first expression is 9r+9r, which simplifies to 18r. The second expression is 81r. These two expressions are not equivalent because 18r does not equal 81r.

Compare Expressions: Compare the first pair of expressions. $\newline$ The first expression is $r+r+r+r+s$ , which simplifies to $4r+s$ . $\newline$ The second expression is $5rs$ . $\newline$ These two expressions are not equivalent because $4r+s$ does not equal $5rs$ .
Compare Expressions: Compare the second pair of expressions. $\newline$ The first expression is $4(8r)$ , which simplifies to $32r$ . $\newline$ The second expression is $12r$ . $\newline$ These two expressions are not equivalent because $32r \neq 12r$ .
Equivalent Expressions: Compare the third pair of expressions. $\newline$ The first expression is $4r+8s$ . $\newline$ The second expression is $8s+4r$ . $\newline$ These two expressions are equivalent because addition is commutative, meaning that the order of the terms does not matter.
Compare Expressions: Compare the fourth pair of expressions. $\newline$ The first expression is $9r+9r$ , which simplifies to $18r$ . $\newline$ The second expression is $81r$ . $\newline$ These two expressions are not equivalent because $18r$ does not equal $81r$ .
