Um , is the equation 2x^3y? or is it 2x*3y?

anonymous · Answer

2x*3y .

anonymous · Answer

ook so to put it in standard for we must have the biggest power first, 

I do not thing the answer will be B or D just from sense. So ou are left with
A ) 2x3y+7y^2x-3x^2-12y
c) 7y^2x-12y+2x^3y-3x^2

But i am not sure from there, im sure someone else will know. If i had to guess i would say A just because the powers are in more numerical order.
