A set of 4 consecutive even integers has a sum of 148. what is the least of these integers

The parabola x = y² - 9 opens: a.)up b.)down c.) right d.)left

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.

3x = 729 solve for x plz . it's urgent. will mark
