A regular polygon is drawn in a circle so that each vertex is on the arce and is connected to the the central angles has a measure of 40% How many sides does the poligon have? 8 9 10 12

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
