HEL WILL GIVE BRAINLIEST A water pump can produce 280 gallons in 24 hours

How many gallons per hour is this?

6720

Step-by-step explanation:

you you are going to multiply 280 gallons and 24 hours to get 6720 I'm not 100% sure this is the correct answer

- 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
