(-7)+13=6
(-7)-13=(-20)
Therefore A and C are the possible coordinates
2y^2 (3x+5z)
6xy^2 + 10zy^2
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.
45 is 75% of 60.
45/60 = 0.75.
Just as 60 * 0.75 = 45
Or 45 / 0.75 = 60
