Help me out with all of this

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.

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

Drag each equation to the correct location on the table. for each equation, determine the number of solutions and place on the appropriate field in the table.
