If ob = 17 and ab = 30, then or = 8 13 23

Find the greatest common factor of -30x 4 yz 3 and 75x 4 z 2.

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Which spreadsheet would be used to compute the first nine terms of the geometric sequence a^n=32•(1/2)n-1
