Pls doo all of them and make sure it's correct

12. Describe all the ways that two planes can interact. Draw a sketch of each. Be specic. 13. a) Solve: 4x+y+z=2 5x 3y + 22 = 5 x 2y + z = 3 b) Describe the geometric representation of the three planes [4. The line of intersection of the planes H1: 23: + y 32 = 3 and H2:x 2}! + z = 1 is L. a) Determine parametric equations for L b) If L meets the xy- plane at point A and the z axis at point B, determine the length of line segment AB
