Factor completely. x^3 + 2x^2 - 15x

a. -3x(x+5)(x+1)
b. x(x+5)(x+3)
c. x(x-3)(x+5)
d. 5x(x+1)(x-3)

Step-by-step explanation:

c x( x+5) (x-3)

Step-by-step explanation:

x^3 + 2x^2 - 15x

First factor out the greatest common factor x

x( x^2 + 2x - 15)

What 2 numbers multiply together to give us -15 and add together to give us 2

5*-3 = -15

5+-3 = 2

x( x+5) (x-3)

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

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
