For the answer to the question above, I'll provide my solutions below.
x² + 4 = 0
<span> - 4 - 4
</span> x² = -4
x = +2i
x² - 6x + 1 = 0
x = -(-6) +/- √((-6)² - 4(1)(1))
2(1)
x = 6 +/- √(36 - 4)
2
x = <span>6 +/- √(32)
</span> 2
x = <span>6 +/- 2√(2)
</span> 2
x = 3 + √(2)
x = 3 + √(2) x = 3 - √(2)
I hope this helps.
The answer is B) <span>(60 - 4x)(50 + 2x) = 2,800
The revenue without any change in price is:
$60/student x 50 students = 3,000
Every price drop reduces the price/student by four, so the first term, which describes the fee per student, is 60 - 4x
Every price drop also increases the number of students by two, so the second term, which describes the number of students, is 50 + 2x</span>
