Answer:
$45.8
Step-by-step explanation:
32.06 / 14= 2.29
2.29x20=45.8
Answer:
The third choice: -4, 0, and 1
Step-by-step explanation:
Finding zeroes is another way of saying solve...set the equation equal to zero and solve..
0 = 2x³ + 6x² - 8x
0 = 2x(x² + 3x - 4) (factor out a 2x from all three terms)
0 = 2x(x + 4)(x - 1) (factor x² + 3x - 4)
So
2x = 0 then x = 0
x + 4 = 0 then x = -4
x - 1 = 0 then x = 1
Our zeroes are -4, 0, and 1
