A group of four roommates make three pots of coffee each day. A pound of coffee beans makes x pots of coffee. If the roommates have no coffee left when they purchase a pound of coffee, how many days will pass until they need to purchase their next pound of coffee

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

i believe the answer is d.

hope it you! : d

x = 23.78
