Which of the following best describes the figure?

a. convex octagon

b. regular octagon

c. concave octagon

d. not a polygon

c. Concave octagon.

Step-by-step explanation:

We have been given an image of a polygon and we are asked to determine the type of our given polygon.

Upon looking at our given image we can see that it has 8 sides and 8 vertices, so our given polygon is an octagon.

Since it has two angles pointing inward, therefore, our given polygon is an concave octagon and option 'c' is the correct choice.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

i believe the answer is d.

hope it you! : d
