Draw the image of the rectangle of the triangle with vertices E(2,1),F(1,2), and G(-2,2) under a dilation with a scale factor of -2 centered at the origin.

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 "

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
