I don't know exactly what you mean by typing like this 2y3(4x-3y). I assume that means 2y cubed (2y^3) or 2y³ times (4x-2y)

Question

I don't know exactly what you mean by typing like this 2y3(4x-3y). I assume that means 2y cubed (2y^3) or 2y³ times (4x-2y)

That becomes 8xy³ -6y⁴

Expand all the parenthesis, then gather like terms, and add them.

2. 12x-3y+x+2y 3(4x-3y)+3y 4(4-2y)-3x+7y

5. 3(r-1)-4r+5 2(3-2r)-4(2-r -r+7+3r-9-2r

7. 3(2b-a)-(2a-b (a=2b)-(b+2a) (A+2B)-(a-b)

Please help. You guys might think you are giving me the answers. If you want you can tell me how to do the problems and I will figure it out. THANK YOU SO MUCH IF YOU HELP ME!!!!!!!!!!!!!!!!!!!
