Answer all three please and thanks

1. Find a scalar equation for the plane passing through the point (5, 2, -3) and having the normal vector [-2, 4, 5]. 2. Find a vector equation for the plane passing through the points (2, -1, 8), (5, 0, 4), and (-3, 2, 5). 3. A plane has the scalar equation 3x - 2y + 5z + 8 = 0. Give the scalar equation of a plane that is a. Parallel to the original plane, but has different values for A, B, and C. b. Perpendicular to the original plane
