Find the perimeter of the regular polygon.

The perimeter is equal to 240.

Step-by-step explanation:

Since  the shape is a regular polygon, the sides are equal to each other, so those two equations are equal to each other.

So, to solve for x, then to find perimeter, we need to set the equations equal to each other.

5x + 10 = 7x + 4

Subtract 5x  and -4 from both sides.

6 = 2x

Divide each side by 2.

3 = x

Now, we plug it into one of the equations and multiply by 6 (6 sides in the regular polygon).

5( 6 + 2 )

40

40 * 6 = 240

The perimeter is equal to 240.

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
