Which of the following is a factor of x3 - 4x2 - 18x + 9?
a.) x – 2
b.) x + 3
c.) x – 5
d.) not factorable

B

Step-by-step explanation:

factorization for 4x^2-18x+9

(x+3)(x^2−7x+3)

the answer is n

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
