Answer:

P(x) = x³ - 3x² - 5x + 15

Step-by-step explanation:

∵ The roots of the polynomial are -√5 , √5 , 3

∴ The polynomial has 3 factors:

  (x - √5) , (x + √5) , (x - 3)

∴ P(x) = (x - √5)(x + √5)(x - 3)

          = (x² + √5x - √5x - 5)(x - 3)

          = (x² - 5)(x - 3) = x³ - 3x² - 5x + 15

∴ P(x) = x³ - 3x² - 5x + 15

A beekeeper pours honey into jars. Each large jar holds 18 ounces of honey. Each small jar holds 12 ounces of honey. The beekeep
ArbitrLikvidat [17]

Answer: 1100 ounces because 20 × 30 + 10 × 50 = 1100

Step-by-step explanation:

Amount of honey contained in each large jar = 18 ounces

Number of large jar filled = 32

Total amount of honey in large jars:

= 18 ounces × 32

= 576 ounces

Amount of honey contained in each small jar = 12 ounces

Number of small jars filled = 46

Total amount of honey in small jars:

= 12 ounces × 46

= 552 ounces

The total amount of hones in the jars will be the addition of the honey in the small and large jars. This will be:

= 576 ounces + 552 ounces

= 1128 ounces

The most reasonable estimate will be:

1100 ounces because 20 × 30 + 10 × 50 = 1100
