-9/4, -2.1 , -26/13, -13/8 you can double check by inserting all these into a calculator so u can see in decimal form and basically the bigger the number that’s negative the less value it is (sorry that’s kind of a bad explanation but i hope this helps :) )
We could use Euler's polyhedron formula:
I believe the answer would be 6x + 9
Is that a test or just regular homework? If it is a test I can't help you.
assuming you mean y² = 169
then taking the square root of both sides gives
y = 
= ± 13
since 13² = 169 and (- 13)² = 169
