ill post it here in a bit, hold on please

Answer 2

if ghjk=24 and ghkl=0, which of the following must be true?
a) \[g >0\]
b)\[h >0\]
c)j=0
d)k=0
e)l=0

Answer 3

my answer was E. L=0 is that correct? @mathstudent55

Answer 4

j and k cannot be zero bec it would make the first product zero.
That eliminates choices c) and d)

Answer 5

We don't know for sure g>0 or h>0 bec in each case we don't know what the other variable is, and we need a positive first product.
You are correct. The only thing we know for sure is \(l = 0\)

Answer 6
