You can round 406to420 then divide by 7 or 406-490 divided by 7
Remark
The number of faces reaching out in the 3rd dimension of the pyramid = the number of edges on the base.
Givens
Number of edges (or sides on the base)= e
Number of faces = f
Formula
F = e + 1 Don't forget that the base is also a face.
The answer is -12x^4y^4 !
It would be -140=x... to get this you would multiply x over 14 by 14... since you did it to one side then you have to do it to the other
