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
A) x³ - 64 = x³ - 4³
In B, 4 is not a cube number.
In C, this is the sum of a cubes. 8x³ + 27 = (2x)³ = 3³
In D, 4 is not a cube number.
Your answer is A.
Question #6
5x³ - 40
5[x³ - 8]
5[x³ - 2³]
Note: x³ - y³ = (x-y)(x² + xy + b²)
5[(x-2)(x² + 2x + 2²)]
5[(x-2)(x² + 2x + 4)]
Your answer is B.

What is irrational number?
An irrational number is a type of real number which cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio. If N is irrational, then N is not equal to p/q where p and q are integers and q is not equal to 0.
Given:
0.6 bigger than 0.6 repeating
0.6 repeating means 0.66666.
and the another we have 0.6.
So, on comparing
0.666666....> 0.6
Hence, 0.6 is not greater than 0.6 repeating.

A set of ordered pairs where each first element is paired with one and only one second element and no element in either pair is without a partner.
Step-by-step explanation:
Question 1: Calculate the slope, x-intercept and y-intercept of a linear equation, f(x) = 5x + 4 ?
Solution:
Given,
f(x) = 5x + 4
The general form of a linear equation is,
f(x) = mx + c
So,
Slope = m = 5
Substitute f(x) = 0,
0 = 5x + 4
5x = -4
x = −45
The x-intercept is (−45, 0)
Substitute x = 0,
f(x) = 5(0) + 4
f(x) = 0 + 4
f(x) = 4
The y-intercept is (0,4)
