Jonathon has a coin jar in which he is saving his loose change. He dumps out all of his coins and
counts that there are 78 total coins, some dimes
and some pennies. After wondering why he
doesn't have any nickels or quarters, which just
seems odd, he counts his money and finds that
he has $3.30. How much are all of his dimes
worth?

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.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
