We can use ratio's to solve
2 books out x books out
------------------- =-----------------------------
3 books in 18 books in from Val
Using cross products
2 * 18 = 3 *x
Divide each side by 3
2*18 /3 = 3x/3
2*6 = x
12 =x

Answer:

Step-by-step explanation:
The given polynomial has zeros at:
x=−3, x=−1, and x=1.
This means that:
x+3, x+1, and x-1 are all factors of this polynomial.
The factored form of this polynomial is :

We expand the last two factors using difference of two squares.




This is the standard form because it is now in decreasing powers of x.
Answer:
28
Step-by-step explanation:
2x-3y+z=-3 , x-5y+7z=-11 , -10x+4y-6z=28
Answer:
The constant is 2 and 11
Step-by-step explanation:
A constant is a number that always has the same value. In this equation 2 and 11 are the constants because they stay the same. 3x doesn't stay the same because 3 is multiplying x.
