is the correct answer
A there are no real zeros
using the discriminant b² - 4ac to determine the nature of the zeros
for y = x² + 4x + 5 ( with a = 1, b = 4 and c = 5 )
• If b² - 4ac > 0 there are 2 real and distinct zeros
• If b² - 4ac = 0 there is a real and equal zero
• If b² - 4ac < 0 there are no real zeros
b² - 4ac = 16 - 20 = - 4
Since discriminant < 0 there are no real zeros
Answer:
8 cookies for each student that was present
Step-by-step explanation:
11 total dozens
10 dozens were separated throughout the present students
He has a TOTAL of 19 students but FOUR were absent
19-4=15
a dozen is 12
so 12x10=120
120 divide by 15 = 8
