Could use some help thanks

5. For a = 5, -1, 3, b = [-3, 2, 0], and c = [1, 4, -2], calcu- late (b x c) x a and b x (c x a). 6. Use the cross product to find the area of the parallelogram made by the vertices (4, 2, 0), (10, 4, 0), (5, 4, 0), 11, 6, 0). 7. Use the scalar triple product to calculate the volume of the tetrahedron with vertices (1, 1, 1), (5, -7,3), (7, 4, 8), and (10, 7, 4). 8. Find the equation of the plane passing through (1, 3, 4), (1, -2, 6), and (4, 0, 7)
