(6x-9)(8+5x-5)=(6x-9)(5x+3)=

$=6x\cdot5x-5x\cdot9+6x\cdot3-9\cdot3=\\=30x^2-27x-27$

Answer: 20x squared -33x-27

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.
