Which of the following are true about x? check all that apply.

x∈B

x∈A∪B

x∈A∪C

x∈A∩B

Step-by-step explanation:

As can be seen from the Venn diagram, x is the shaded portion between the intersection of 3 circles A, B and C.

hence x belong to b, and x belong to A union B, x belong to A union C and x belong to A intersection B !

the answer is 5636.7

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.
