“The flounder fish can swim at a depth of 66 meters below sea level. The killer whale swims at a lower elevation than the flounder fish. Which of the following could be the elevation of the killer whale?” PLEASE HELPPP MEEE

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

answer:  

123455421

step-by-step explanation: easy

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.
