In complete sentences explain how you would factor the numeric expression 34 + 12 + 20. Then provide an example of a numeric expression that can be factored, and factor that expression.

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.
