This is not a true statement
Answer:
19 units
Step-by-step explanation:
A regular polygon has equal-length sides. This fact can be used to solve for the value of x, and for the side length. Knowing the side length, we can find the perimeter.
__
<h3>side length</h3>
5 -2x = 4x +9 . . . . . marked sides are the same length
-4 = 6x . . . . . add 2x -9
-2/3 = x . . . . . divide by 6
5 -2(-2/3) = 5 +4/3 = 6 1/3 . . . . length of one side
<h3>perimeter</h3>
The perimeter is the sum of the side lengths, or 3 times the length of one side.
P = 3s = 3(6 1/3)
P = 19 . . . . units
The perimeter of the polygon is 19 units.
X will be 50 if I'm not wrong
It is given in the question that
Ms. Lu is adding a new room to her house. The room will be a cube with volume 4,913 cubic feet.
Let the length of the side of the puppy be x ft .
And the formula of volume of cube is

Substituting the given values of volume, we will get

So the length of the sides of the room is 17 ft .
