21 Zach has 958 pennies. He
exchanged them for nickels. How many
nickels did she get?

1 penney= 0.2 nickels

so 958 pennies = 958×0.2

= 191.6 nickels

Therefore zach got 191.6 nickels

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.

hi! i think the answer is 1/2 : )
