Answer:
c = 81
Step-by-step explanation:
The equation x² -c = 0 can be factored as ...
(x -√c)(x +√c) = 0
which has roots ±√c.
The roots are given as ±9, so we have ...
±9 = ±√c
c = (±9)² = 81
The value c = 81 makes the equation have ±9 as solutions.

Answer: 86
deducting the price for the day; 41.50 - 20.00 = 21.50
next, dividing the new quotient; 21.50/0.25 = 86
we divide by 0.25 because the cost is 0.25 per mile and the total is 21.50 (without 20$ for the rent per day)
