What is the answer to this question? Please give me the short answer and long answer.

Each triangle weighs 3 grams.

Step-by-step explanation:

On the left side, there are 6 squares (12 grams) 3 circles (9 more grams), and 2 triangles (2x grams).

On the right side, there are 3 squares (6 grams) 2 circles (6 grams), and 5 triangles (5x grams).

This makes the equation 21 + 2x = 12 + 5x.

Let's find x.

21 + 2x = 12 + 5x

Subtract 5x from both sides.

21 - 3x = 12

subtract 21 from both sides.

-3x = -9

Divide by -3.

x = 3.

Each triangle weighs 3 grams. Let's prove this.

21 + 2x = 12 + 5x

21 + 2(3) = 12 + 5(3)

21 + 6 = 12 + 15

27 = 27

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

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.
