I think it's B, there no repeating number.
Y is greater than or equal to 5. It says no less than, making the equal to possible.
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.

Answer:
Step-by-step explanation:
2x(x - 3) + 7(x - 3)
2x^2 - 6x + 7x - 21
reduce
2x^2 + x - 21
if this is equal to 0 then:
2x^2 + x - 21 = 0
factored:
(2x + 7)(x - 3) = 0
How that was done:
Divide the (2x^2) into (2x) and (x).
Divide the (-21) into (+7) and (-3). You choose these numbers so that their sum, when multiplied by (2x) and (-3), adds up to (+x).
