According to the given cubic equation 8x³-10x² - 21x + 18 = 0 the other value of x will be 4.
<h3>How does one solve a three-degree equation?</h3>
Traditionally, a cubic problem can be solved by converting it to a quadratic equation and then solving it using factoring or the quadratic formula. A cubic equation, like a quadratic equation, has three roots.
<h3>What is the simplest method for solving a cubic equation?</h3>
The typical strategy for solving a cubic problem is to convert it to a quadratic equation and then solve the quadratic using the standard methods, either factoring or using the formula. All of them are cubic equations. A cubic equation, like a quadratic equation, may have two or three real roots.
<h3>According to the given data:</h3>
8x³-10x² - 21x + 18 = 0
x= 2
substituting the value in the equation we get:
8x³-10x² - 21x + 18 = 0
8(2)³-10(2)² - 21(2) + 18 = 0
68 - 40 - 42 + 18 = 0
4 = 0
According to the given equation 8x³-10x² - 21x + 18 = 0 the other value of x will be 4.

X + 1/6 = 6...subtract 1/6 from both sides
x = 6 - 1/6 ...common denominator is 6
x = 36/6 - 1/6
x = 35/6 or 5 5/6
OR
x + 1/6 = 6....multiply everything by common denominator of 6
6x + 1 = 36
6x = 36 - 1
6x = 35
x = 35/6 or 5 5/6
Tim wrote a statistical question because he is trying to figure out how many books were read in total. Jenna just wanted to know what the first book on the list was.
Answer:
X=5 and a quarter
Step-by-step explanation:
21 + 21 = 4x + 4x
42 = 8x
8x = 42
x = 42/8
= 5 1/4
I am certain the answer is C. Algebra properties are used in proofs. Postulates are definitely used. And definitions are explanations. So, it is C.
