Answer:
1. 3/8
2.2/3
That’s the answer. I’m positive!!
That is a fraction, if you want to put it into decimal form, it would be equivalent to 0.7
Answer: -3
Step-by-step explanation: If you're giving your friend 3 cookies, it's a decrease which means that it's negative.
So giving your friend 3 cookies can be written as -3.
3(b+f) you just do the sum and times it by 3
First, we could try to factorize the polynomial. We could group the first and third terms, and the second and fourth term:

Now, x(x^2-9) is a common factor:

.
By the difference of squares formula, our final factorization is :
x(3x-1)(x-3)(x+3).
Here we can see clearly that the roots of f(x) are 0, 1/3, 3, and -3.
Remark: we grouped the terms in pairs as we did, noticing that the ratio of the exponents, and coefficient in each pair was the same.
Answer: 0, 1/3, 3, and -3.
