8+ 12x is an equivalent expression to 2 + 2x + x + 6x + 2x +6. Which statement below proves this to be true or false?

a. They are equivalent because when you add the like terms together you get 8 + 12x.

b. They are equivalent because when you add all the terms together you get 8x + 12.

c. They are not equivalent because when add all the terms together you get 19x.

d. They are not equivalent because when you add the like terms together you get 8 + 11x.

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.
