Answer:
Option 1
Step-by-step explanation:
Counter-intuitively, the correct answer is option 1. Option 2 is obviously a cross section, since it is the shape of the base of the triangle. Option 3 is also obviously a cross section, since the figure is a triangular prism. Option 4 is a cross section because, if you slice diagonally, you may create a cross section with a wider base on the bottom and larger on top. However, it is impossible to create a cross section of a rectangle from this square pyramid. Hope this helps!
The answer is 9bt if you gave me the rest of the question I would maybe be able to get the real answer.
To write the problem out as an equation, let 'n' equal your number.
(15 x 1/n) - 3n
Replace the x with n:
f(n) = 2n+1
