Discriminant of a quadratic equation can be calculated as:
Discriminant = b² - 4ac
b = coefficient of x term = 2
a = coefficient of squared term = 1
c = constant = 7
So,
Discriminant = 4 - 4(1)(7) = -24
So, the correct answer to this question is option C
Answer:
35
Step-by-step explanation:
10/12 of an hour/60 minutes = 50 minutes so they spent that amount of time doing daily exercises
1/4 of an hour/60 minutes = 15 minutes so they spend that time hiking
subtract the 15 mins of hiking from the total 50 of exercises = 35 for other body exercises
Hope this helped!

Answer:
area = 2236 in²
Step-by-step explanation:
area of a triangle = 1/2 b h
b = 86
h = 52
plug in values
area = 1/2 * 86 * 52
area = 2236 in²
