Answer:
8, 10
Step-by-step explanation:
Multiplying the equation by the product of the denominators, we have ...
40(x+2) +40x = 9x(x+2)
80x +80 = 9x^2 +18x . . . . eliminate parentheses
9x^2 -62x -80 = 0 . . . . . . put in standard form
9x^2 -72x +10x -80 = 0 . . . prepare to factor by grouping
9x(x -8) +10(x -8) = 0 . . . . . factor pairs of terms
(9x +10)(x -8) = 0
Solutions are ...
x = -10/9 and x = 8
The integers are 8 and 10.

Answer:
For 1 cup of peanut Kevin will use
of raisins.
Step-by-step explanation:
Given:
cups of peanuts =
cups of raisin
can be rewritten as
cups of peanuts =
cups of raisin
We need to find number of cups of raisins used in 1 cup of peanut.
Solution:
Now we know that;
cups of peanuts =
cups of raisin
So 1 cup of peanut = number of cups of raisins used in 1 cup of peanut
Now by using Unitary method we get;
number of cups of raisins used in 1 cup of peanut = 
Hence For 1 cup of peanut Kevin will use
of raisins.
