Doing a little SAT prep... What the fuck is the difference between

>>201789
bump

>>201765
Technically both answers are correct.
Practically the person who made this question is a retard.

>and=both right
>or=one right

I guess

>>201765
at exactly .6 and 5.9 seconds is more right than .6 or 5.9 seconds logically.

>>201765
When you say .6 or 5.9, you're implying that if one is true, the other doesn't have to be, but in this case, both of them have to be true.

>>201841
Not necessarily

And it's common to see answers to a quadratic in the form of

t = 0.6 or t = 5.9

>>201854
If you are asked to find the roots of a quadratic, and you know it passes the x axis twice, then there is no OR. (x && b) != (x || b)

Alternative remains true if both options are true
