Step-by-step explanation: So u have (6x-9-2x) (8+5x-5) first you want to combine like terms. 6x-2x = 4x and 8-5 = 3 so u end up with (4x-9) (3+5x) if u follow the FOIL method u will end up with 12x+20x squared -27-45x. Last combine like terms again and the answer is 20x squared -33x-27 and I got the answer correct on Edmentum.
ok so if the bird is on the top at 15 and a half then goes down six feet substrate 15 and a half from six and you get nine and half from the ground to the bird
