Answer: 5n - 4
Answer:
9 scoops of flour
Step-by-step explanation:
1 scoop of flour per 5 cookies
5 + (n - 1)²
5 + (n - 1)(n - 1)
5 + (n² - n - n + 1)
5 + (n² - 2n + 1)
n² - 2n + 1 + 5
n² - 2n + 6 = 0
n = <u>-(-2) +/- √((-2)² - 4(1)(6))</u>
2(1)
n = <u>2 +/- √(4 - 24)</u>
2
n = <u>2 +/- √(-20)
</u> 2
n = <u>2 +/- 2i√(5)</u>
2
n = 1 <u>+</u> i√(5)
n = 1 + i√(5) n = 1 - i√(5)
The answer is equal to B.
