Consider the planes given by the equations 2x−3y−5z=2,
2x−2y+3z=4.
(a) Find a vector v⃗ parallel to the line of intersection of the planes.
v⃗ =
(b) Find the equation of a plane through the origin which is perpendicular to the line of intersection of these two planes.
This plane is

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
