A sack of potatoes weighs 14 pounds 9 ounces after wendy makes potato salad for a picnic the sack weights 9 pounds 14 ounces wha
dlinn [17]
For this case we have the following conversion:
 1 pound = 16 ounces
 Then we rewrite the sack weights:
 14 pounds 9 ounces = 14 9/16
 9 pounds 14 ounces = 9 14/16 = 9 7/8
 Then, we subtract both values:
 (14 9/16) - (9 7/8) = 4.6875 = 4 + 0.6875
 Rewriting:
 4 + 0.6875 = 4 + 6875/1000
 4 + 1375/200 = 4 + 275/40
 4 + 275/40 = 4 + 55/8
 Answer:
 
the weight of the potatoes wendy use for the potato salad is:
 
4 + 55/8 pounds

Answer this question :)
wariber [46]

Hey there! :)

Answer:

f(x) = x³ -6x² -16x. (Simplified)

Step-by-step explanation:

Given:

Zeros: -2, 0, 8; degree: 3

To begin, write the polynomial in factored form involving the zeros:

f(x) = x(x + 2)(x - 8).

If you were to convert this to standard form, you would FOIL the factors:

f(x) = x(x + 2)(x - 8)

f(x) = x(x² -6x -16)

f(x) = x³ -6x² -16x. This is your equation in standard form.
