Which of the following is not a polynomial identity? A- x^2+y^2=x^2+2xy+y^2 B- x^2-y^2=(x+y)(x-y) C- x^3+y^3=(x+y)(x^2-xy+y^2) D- (x+y)^2=x^2+2xy+y^2

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically

cause it equals more

54/3 is 18 so 18 is your answer
