Answer 2

I honestly don't know its just an empty box

Answer 3

really?? that's so weird

Answer 4

yea I know and I don't know how to answer it

Answer 5

well if you let p = -7
and r = 7

this fits the definition, because p = -r

so let's do the last 3
-7 + 7 = 0 < 0 is false
-7 - 7 = -14 < 0 is true
7*-7 = -49 < 0 is true

Answer 6

oops, -7 - (-7) = -7 + 7 < 0 is false

Answer 7

only the last one is true

Answer 8

thank you
