Step-by-step explanation:
A seems complicated and doesn’t make an sense while D is simple
The 3rd one. (where the round part of the graph is at 0, 0) because that is where the y axis meets
Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length), (x+y) (width), and (x-y) (height)
