4. Triangle XYZ is graphed on a coordinate grid with vertices at X(-2,5), Y(-1,-7), and Z(2,-4). Triangle XYZ is dilated by a scale factor of u with the origin as the center of dilation to create triangle X'Y'Z'. Which ordered pair represents the coordinates of the vertex Y'? A. (-1 + U, -7 + u)
(Yellow Hearts)
B. (-1 -u, -7 - u) (Red Hearts)
C. (-1u, -7u) (Pink Hearts)
D. (-7,-) (Green Hearts)​

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 "
