Answer:
First option: 
Second option: 
Fourth option: 
Step-by-step explanation:
Rewrite each equation in the form
and then use the Discriminant formula for each equation. This is:

1) For
:

Then:
Since
this equation has no real solutions, but has two complex solutions.
2) For
:

Then:
Since
this equation has no real solutions, but has two complex solutions.
3) For
:

Then:
Since
this equation has one real solution.
4) For
:
Then:
Since
, this equation has no real solutions, but has two complex solutions.
Equation = 12 - -24 = ?
After keep, change, flip: 12 + 24 = ?
Answer = 36
Yes. all the friends will get at least one cup of juice
#4 is D 8.5 oz, do 3.4 / .4
#5 is C .96$, do (3/4)x=36 and you get 48 x .02 and you get .96
if this helps please mark branliest, Trying to rank up haha
