The product of two rational numbers is 2/5 , if one of them is -8/25, find the other. With steps explained.

Product of two rational numbers =

One of the number =

The other number.

The other number is .

Let the other number be .

As per the question, we have

➺ L. H. S. = R. H. S.

Hence verified.

correct answer:

a + bi

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.
