Use the triple scalar product to find the volume of the parallelepiped having adjacent edges given by the vectors u = (8, 7,2), v = (7, -2,3), w = (-8,4,1} O 305 O 52 O 152 O 309 O 228Find an equation of a plane passing through the following three points. (1, -1, -1), (-3,2,5). (4,4,5) O -12x-42y+ 29z -25 = 0 O 12x-42y + 29z - 25 =0 O 12x -42y + 29z + 25 =0 O 12x+ 42y + 29z -25 =0 ( 12x-42y -29z - 25 =0
