Answer:
When 
Step-by-step explanation:
When 
is smaller than 
, the resulting value under the square root will become negative. Since it is impossible to take the root of a negative number, the expression is thus undefined, however, it can be represented with the imaginary number 
where = 
.

See explanation
Step-by-step explanation:
Car A: Started at 0 and ended at 300, thus, car A travels 300 miles.
It travels 6 hours, so car A speed is 
mph.
Car B: Started at 100 and ended at 300, thus, car B travels 300-100=200 miles.
It travels 5 hours, so car B speed is 
mph.
Since 50>40, car A traveled faster than car B.
The graph for the car A is steeper than the graph for the car B.
The number of months when the gyms cost the same is 5 months.
<h3>When would the cost be the same?</h3>
Total cost of joining the gym = registration fee + (cost per month x number of months)
- Hunkey Heros = $50 + $20m
- Zipity-zapity- zap-that-fat = $70 + $10m
When the gyms costs are the same, the two above equations would be equal to each other:
50 + 20m = 70 + 10m
20m - 10m = 70 - 20
10m = 50
m = 50 / 10
m = 5
