Answer:
Therefore, Option 1 is correct.
Step-by-step explanation:
We have been given the quadratic equation:
If we compare it will general quadratic equation which is: 
Here, a=5,b=3 and c= -4.
Now, we will use the formula:
And then 
Where,
Therefore, Option 1 is correct.
The answer would be b because AC don’t make sense
Answer:
477.09 mi/da
Step-by-step explanation:
If student must use conversion given, 3.28ft = 1m, then the following works:
32km/hr = ______mi/da 1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft
32km/hr x 24hr/day x 1000m/1km x 3.28ft/1m x 1mi/5280ft = 477.09mi/da
If student can use 1km = 0.62mi, some steps can be skipped.
Step 1: Convert the denominators to the same number.
1/9 = 2/18
2/3 = 12/18
5/18
Step 2: Add the numerators.
12 + 2 + 5 = 19
Step 3: Convert to mixed number.
19/18 = 1 1/18
Hope this helps! :)
