Given ? = 10 inches and A = 40 square inches, solve A = lw in terms of w, then substitute values. (1 point)
W = 10 inches
W 400 inches
w = 4 inches
w = 40 inches

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.
