Awhole number is represented by n. which statement is true about n and -n?
a. their sum is zero
b. their difference is zero
c. their product is zero
d. their quotient is zero

A and B

Explanation: A sum is an answer to an addition problem and a difference is the answer to a subtraction problem. N is the sum to the addition problem and -n is the answer to a subtraction problem.

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.
