Given a quadratic equation 
, we define the discriminant as
The number of real solutions of the equation depend on the sign of 
:
- If
the equation has two solutions - If
the equation has one double solution - If
the equation has no real solutions
In this case, we have
And so this equation has no real solutions.
The correct answer is 5 1/2 because if it weren’t simplified it would be 6/2 which makes the numerator the greatest.
Answer:
38.01
Step-by-step explanation:
Let's see how many pages he spellchecks in 1hrto start with,
20min is 1/3 of an hr so multiply both numbers by 3
20*3=60min or 1hr
14*3=42
So he spell checks 42 pages in an hour now let's multiply that by 5.5
1hr*5.5=5.5hrs
42*5.5=231
He spellchecks 231 pages in 5.5 hrs
