Please help me out on this problem

-3

Step-by-step explanation:

First step to this is to replace the variables with their coordinated values. Remember to use parentheses.

4(2)-2(2+4)+1=?

We can start to simplify.

4(2)-2(6)+1

Then---

8-12+1

-4+1

Final Answer (-3)

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.

your answer is the frist one
