Answer: -12.35
Step-by-step explanation: Hope this helps!
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.

Answer:
NO = 10
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle, then it is half the length of the third side, that is
18 - 2x = (9x - 16) ( multiply both sides by 2 to clear the fraction )
36 - 4x = 9x - 16 ( add 4x to both sides )
36 = 13x - 16 ( add 16 to both sides )
52 = 13x ( divide both sides by 13 )
4 = x
Then
NO = 18 - 2x = 18 - 2(4) = 18 - 8 = 10
