Answer: A
Step-by-step explanation:
Answer:
The value of 
is -30.
Step-by-step explanation:
Let 
, we notice that expression is a second order polynomials. We can rearrange the polynomial and use factorization to calculate all roots:
(1)
(2)
(3)
From (3) we find the least root:
![x = \sqrt [3]{\frac{8}{27}}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%20%5B3%5D%7B%5Cfrac%7B8%7D%7B27%7D%7D)
By (2) we have the value of :
The value of x for given polynomial is 8.8.
<h3>What is Polygon?</h3>
The definition of a polygon is given as a closed two-dimensional figure with three or more straight lines.
Here, the length of sides of given Polygon are:
4x, 6x, 12, 18
Perimeter of polygon = 118 units.
We know that,
Perimeter of polygon = Sum of all sides
118 = 4x + 6x + 12 + 18
118 = 10x + 30
118 - 30 = 10x
10x = 88
x = 88/10
x = 8.8
Thus, the value of x for given polygon is 8.8.
