Me, these 2 questions are crazing me out!

#1: -25/52

#2: 16x-8y

Step-by-step explanation:

For the first one *the one that you're simplifying*, you need to turn 2 3/5 into an improper fraction. 2 3/5 will become 13/5.

(-5/4)/(13/5)=(-5/4)*(13/5)= -25/52

For the second one *the one that's the perimeter of the square*, you already know that all of a square's sides are the same length. That means, if one of the sides is (4x-2y), then all of them will be (4x-2y). You can either add them like this: (4x-2y)+(4x-2y)+(4x-2y)+(4x-2y), or just multiply it by 4, which will be:

4(4x-2y)

16x-8y

I hope this helped, even just a little bit! :)

the answer is d

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
