When c = -3 then 4c + 5c - 2 = [4 x -3] + [5 x -3] - 2 = -12 +(-15) - 2 = -12 -15 -2 = -29
Yes, draw the lines from the obtuse angles to the center of the line opposite from it.
A 3D shape has 3 axises (x,y and z), while a 2D shape has only 2 axises (x,y). Or simpler, in 3D dimension you can go up, down, left, right, forward, backward while in a 2D di…mension you can only go left, right, forward, backward, excluding up and down.
