The sum of two numbers is 85. there difference is 9. find the numbers

38 and 47

Step-by-step explanation:

The first number would be = (85-9)/2

= 76/2 = 38

The second number would be either 85 - 38 or 38 + 9 = 47

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.
