Answer:
x=-1
Step-by-step explanation:
first you multiply 3 by whats in the parenthesis (you would get 6x-3)
then on the other side you combine like terms (add 7x plus 5x=12x)
Then you would isolate X to one side by subtracting 6x from 12x
Then you would subtract 3 from the side with 12x
By now your equation would be -6=6x
so you would divide both side by negative six to get x=-1
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
