A packing machine at a factory can fill 50 containers of oatmeal every minute. All of the containers filled to the top by this machine are the same size. How many minutes will it take this machine to fill 825 containers of oatmeal?

16 1/2 minutes

16 1/2

Step-by-step explanation:

1st: divide 825 ÷ 50

2nd: 50 can't go into 8 so you move to 82 and 50mgoes in once

3rd: 82 - 50 = 32

4th: bring down the 5 and then it is 325 and 50 can go into that 6 times

5th: you are left with 25 and 25 is half of 50 so therefore it is 16 and a half

Done!

-2, -2, 1

Step-by-step explanation:

simply substitute each potential answer into f(x) and see which one results in f(x) = 0,

f(x) = x³ + 2x² - x - 2

f(-3) = (-3)³ + 2(-3)² - (-3) - 2 = -8(not a root)

f(-2) = (-2)³ + 2(-2)² - (-2) - 2 = 0(Is a root!)

f(-1) = (-1)³ + 2(-1)² - (-1) - 2 = 0 (Is a root!)

f(0) = (0)³ + 2(0)² - (0) - 2 = -2 (not a root)

f(1) = (1)³ + 2(1)² - (1) - 2 = 0(Is a root!)

f(2) = (2)³ + 2(2)² - (2) - 2 = 12(not a root)

f(3) = (3)³ + 2(3)² - (3) - 2 = 40(not a root)
