Could you solve this show your work as well.

  x = 0.9

Step-by-step explanation:

It is convenient to clear fractions by multiplying the equation by the product of the denominators. That gives ...

  0.5(4x +9) = 3x(7/3)

Multiplying by 2 will give you ...

  4x + 9 = 14x

Subtract 4x

  9 = 10x

And divide by 10

  9/10 = x

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

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.
