Best ResponseYou've already chosen the best response.0look back at the last question. I am not sure you know why they added to 38. I think you might have hurried over that part. Maybe I am wrong? For 4(7b^2  20b 32) we have 4(7b ?)(b ?) which ones should we choose for 32?

Best ResponseYou've already chosen the best response.0We need to get 20 If we take 4 and 8 notice 7 * 4 = 28 1 * 8 = 8 Notice 28  8 = 20 ^ ^        multiplies to make 32  multiples to make 7
