andrey2020 [161]

Answer:

57/100

Step-by-step explanation:

This is the answer because:

1) Since 0.57 in the hundredths place, the denominator is going to be 100

2) We have 57 of a 100, therefore, 57 is going to be the numerator

3) Now, our fraction is 57/100

4) We cannot simplify this fraction any further because they do not have any common multiples or factors

Hope this helps!

Polynomial that represents a difference in cubes.

x³ - 64 = 0
x³ = 64
∛x³ = ∛64
x = 4

Correct Steps for factoring the polynomial 5x³ - 40
5(x³ - 8)
5((x)³ - (2)³)
5(x - 2)(x² + 2x + 4)

To check:
5(x - 2)(x² + 2x + 4)
(5x - 10) (x² + 2x + 4)
5x(x² + 2x + 4) - 10(x² + 2x + 4)
5x³ + 10x² + 20x - 10x² - 20x - 40
5x³ + 10x² - 10x² + 20x - 20x - 40
5x³ - 40
