It is 0.05, all you have to to do is move the decimal to the left.
-6x^3y + 9x^2y^2 - 12xy^3
-3xy(2x^2) - 3xy(-3xy) - 3xy(4y^2)
-3xy(2x^2 - 3xy + 4y^2)
The answer is C.
Y=x2, 72=(6x6), 72=36, 72-36=36. The answer is d. 72=2(6x6)
Input negative 18 into x and distribute. on both sides of the equal sign you should get 70=70
