3 + 2.7x = 9.5 + 3.2x?
work

x = -13

Step-by-step explanation:

 3 + 2.7x = 9.5 + 3.2x

    -2.7x             -2.7x  

3 = 9.5 + .5x

I just moved the 2.7 to the opposite side and combining the like terms.

 3 = 9.5 + .5x

-9.5  -9.5                

-6.5 = .5x

Now you need to isolate the variable by dividing both sides by .5 to get the answer of x = -13

Hope that helps and have a great day!

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.

no one knows lol
