One of the corners of a cube is sliced off. the resulting cross section will have a minimum of how many sides?

The resulting cross-section will have a minimum of three sides.

i.e. a triangle will be formed.

Step-by-step explanation:

Because on cutting a cube along the corner we will obtain a triangle and thus a triangle has three sides.

Hence, the resulting cross section will have minimum of three sides.

( Also we can obtain many other figures on slicing a cube in different ways.

If we slice a cube parallel to the base we will obtain a square.

when we  will slice the cube to it's diagonal we will obtain a rectangle.

and in many other ways)

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
