How would you describe the slice that created the rectangular cross-section on this cake

perpendicular to the base.

Step-by-step explanation:

To Find: How would you describe the slice that created the rectangular cross-section on this cake

Solution :

Cross-section : A cross section is the shape we get when cutting straight through an object.

In this case we observed that since the cake is a rectangular prism then the cross section after the cut is rectangular.

Thus we can conclude that cross section is perpendicular to the base of the cake.

Hence Option D is correct.: perpendicular to the base.

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
