We will solve the problem of subtraction between fractions.
Given:
Kim and Courtney share a 16-ounce of the box of cereal.
By the end of the week:
Question:
What fraction of the box is left?
The Process:
Kim has eaten ³/₈ of the box of cereal. Let's calculate how many fractions of the box are left after Kim has eaten them.
Hence, the rest of the box after Kim has eaten ³/₈ of the box is
Furthermore, Courtney has eaten ¹/₄ of the box of cereal. Let's calculate how many fractions of the box are left again after Courtney ate the remaining part since Kim had eaten it before.
Before we subtract, the denominator must be equated. Prepare ¹/₄ to be ²/₈. The numerator and denominator are multiplied by two.
Thus, the fraction of the box left after Kim and Courtney have eaten is
- - - - - - - - - -
Quick Steps:
The summary scheme is as follows:
Initial conditions
Kim has eaten ³/₈ of the box:
Courtney has eaten ¹/₄ (or ²/₈) of the box:
Final conditions
is subtracted by and is subtracted by equal as the remaining part

Answer:
f(x) = x³ + x² - 8x - 12
Step-by-step explanation:
given roots x = -2 of multiplicity 2 and x = 3, then
(x + 2)² and (x - 3) are factors and the polynomial is the product of the factors
f(x) = a(x + 2)²(x - 3) ← where a is a multiplier
f(x) = (x² + 4x + 4)(x - 3) ← with a = 1
= x³ + x² - 8x - 12
The equation that represents the average of the x-intercept is 3.
Option C is the correct answer.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
f(x) = 4x² - 24x + 20
x-intercept is f(x) = 0.
Now,
4x² - 24x + 20 = 0
4(x² - 6x + 5) = 0
x² - 6x + 5 = 0
x² - (5 + 1)x + 5 = 0
x² - 5x - x + 5 = 0
x(x - 5) - 1(x - 5) = 0
(x - 1)(x - 5) = 0
x = 1 and x = 5
The average of x-intercept.
= (1 + 5)/2
= 6/2
= 3
Thus,
The average of the x-intercept equation is 3.

Answer:
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
You start at (0,0) for the top one, while you start at -4 for the bottom one.
