3000cm because if you look at the variables there is no more letter m's than anything so if you cancel out and see what is equal to 30 then you get 3000cm!!!!!
12x+12 because you do the distribution property and this is how 3*9=27 3*4x=12x 3*-5=-15 27-15 = 12 so 12x+12 would be the answer it is really simple.
3x^2 - 2x^2y + 2xy^2 + 4y^2 + xy^2 - y^2 + 2x^2y
= 3x^2 + 3y^2 + 3xy^2
answer
3x^2
3y^2
3xy^2
