b
Step-by-step explanation:
9 and 8.
The sum equals 17 and the product of the two numbers equal 72.
So plug in 10 for r which would give you 3(10)=10+5s the multiply 3x10 so you should have 30=10+5s you want to get 5s by its self to subtract 10 to both sides so you should get 20=5s them divide 5 to both sides and you get s=4
