Nine more than 3 times a number is the same as 6 less than twice the number

Step-by-step explanation:

Let the number  = x

3x + 9 = 2x - 6  Looks like you are going to get something negative here.

Subtract 2x from both sides.

3x - 2x + 9 = 2x - 2x - 6

x + 9 = -6    

Subtract 9 from both sides.

x + 9 - 9 = - 6 - 9

Combine

x = - 15

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
