Answer:
Step-by-step explanation:
let present age of
Dylan=x
Renee=y
x+y=57
9 years ago
x-9=2(y-9)=2y-18
x=2y-18+9=2y-9
so 2y-9+y=57
3y=57+9=66
y=66/3=22
x+22=57
x=57-22=35
Dylan's present age=35 years
25y
y×25=25y
Quotient: y^2 -2y +3
Remainder = 0
We need to solve he equation:
y^3-4y^2+7y-6 ÷ y -2
It is solved in the figure attached below:
After solving we get
