Question

PLZ help Asap!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation! 

The first one : 
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular".  But a triangle is basically a flat pyramid. 

(I'm typing really fast to help!!!!) 

Second one: Its B!! Look at it really closely! You'll get it!!!

(Going really fast now!!!!) 

Third one: Between B or D!!! But I think you're right on your choice!!!!

(FASTER FASTER!!!) 

FINALLY: Copy and paste your answers into google. People have asked the same question! 

I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
