What should be true about -20 and 20?

-20 and 20 are both composite numbers. They're also the exact opposite.

There are more things that they have in common;

Step-by-step explanation:

You asked, I answered.

Hope this helped! :)

-20+20=0

-20-20=-40

20-(-20)=40

20x-20=400

20/-20=-1

-20/20=1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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.
