19/4rs-8/3r+1/4rs+9

Answer 1

Answer:5

Explanation:

Answer 2

`(19)/(4)rs -(8)/(3)r^2+(1)/(4)rs +9`

The only like terms are 19/4rs and 1/4rs because they have the same variables, so: [I rearranged, to put the like terms next to each other]

`-(8)/(3)r^2+(19)/(4)rs+(1)/(4)rs+9` Since the denominators are already the same, you can combine the fractions

`-(8)/(3)r^2+(20)/(4) rs+9`

`-(8)/(3) r^2+5rs+9`
