Step-by-step explanation:

Attachment 1 : The sum of all exterior angles in any regular polygon will be 360 degrees, so if an exterior angle is found to be 30 degrees, it will have 360 / 30 sides. Therefore 360 / 30 = 12 sides

Attachment 2 : This figure is a concave quadrilateral. You can tell by it's shape, but also as one interior angle, in this case ∠KLM, is greater than 180 degrees.

Attachment 3 : As you can see the missing number is simply sum of the numbers provided on the left. Therefore the missing number will be the following,

1³ + 2³ + 3³ + 4³ + 5³ = 1 + 8 + 27 + 64 + 125

= 125

Attachment 4 : This is an example of the associative property, as it allows you to re - group the numbers. Your solution will be " Associativity. "

Attachment 5 : The cube of a negative integer will always result in a negative integer. Let's take - 3 as an example,

(- 3)³ = - 3 - 3 - 3 = 9 - 3 = - 27
