b. Tìm tham số k để
U = (2,3,k^2 +1) là một tổ hợp tuyến tính của W , và suy ra [U]w .

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 "

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

it would rotate about 180 degrees.
