8-15 and show steps i got like 3 more assignments to do if someone would be kind enough to erase some stress off of me that would be nice

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

the answer is  

c.

14,469 cubic feet

i know this one is right
