Find the value of x, then the perimeter of the regular polygon. I have attached the image that shows the ploygon.

x = 3

perimeter: 18 units

Step-by-step explanation:

1. First, we should know that a regular polygon is a polygon that has all angles  the same angle measure and all sides the same side length.

2. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 7x from both sides.

Step 3: Subtract 10 from both sides.

Step 4: Divide both sides by -2.

Step 5: Check if solution is correct.

3. Now, since this polygon has 6 sides, it's a hexagon. To find the perimeter of a hexagon, we just multiply the length of one side 6 times.

Therefore, x = 3 and the perimeter is 18 units.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
