Answer 9

please i need help

Answer 10

couldent you just use FOIL for the first ones, i dont think there gonna notice know if you use that or a different thing.

Answer 11

I dont think you can

Answer 12

yeah just use whichever method that you think is the easiest. you will get the same answers so it doesnt really matter

im not good at foil

Answer 16

do the best your at.

I dont know what the one I like to do is called but for the first one you would set it up like this:
\[4r(7r+2) -5(7r+2)\]

Answer 18

and than distibute right

Answer 19

then just mulitply. 4r*7r=28r^2 then 4r*2= 8r. do the same with the next parenthesis then add together the like terms.
