You know you have two hours which will be the whole number. Then you take 36min and put it over 60min (total number of min in an hour) and you simplify by 6 to get 6/10 which can be simplified again to 3/5 so your final mixed number is
2 and 3/5 hours

You can use the quadratic equation to solve this once you have this set equal to zero. The answers would be roughly 9.6 and -0.6.
Answer:
Rational
Step-by-step explanation:
Quick Easy Eliminations:
We can get rid of positive integer as the sum of these roots is a decimal which is not a whole number. Hence, we can eliminate 2 options, C. Positive integer and D. Whole Number.
First solve:
6√14 + √14
= 7√14 (Decimal form: 26.191602)
What we need is the decimal form in order to determine if it's rational or irrational.
A rational number is any integer, fraction, terminating decimal, or repeating decimal.
Rational
B. 4(4a+5)
4 would multiply all what’s in the bracket
16a +20
