Answer:
A)
Step-by-step explanation:
the solution of a squared equation is
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = 8
c = 22
x = (-8 ± sqrt(64 - 88))/2 = (-8 ± sqrt(-24))/2 =
= (-8 ± sqrt(4×-6))/2 = (-8 ± 2×sqrt(-6))/2 =
= -4 ± sqrt(-6) = -4 ± i×sqrt(6)

Answer: B is reasonable
Step-by-step explanation: In 4 hours, you hike 10 miles. Divide 10 miles by 4 hours to get miles per hour, which is what you want to solve for in this problem. 10 divided by 4 is 2.5, which means you can hike 1 mile in 2.5 hours.
