Answer:
See below
Step-by-step explanation:
<u>Given function</u>
<u>We can find its factors:</u>
- x³ + 3x² - 7x - 21 =
- x²(x + 3) - 7(x + 3) =
- (x² - 7)(x + 3)
We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)
Also one of zeros of the function is -3
The answer is: x = 2 ∨ x = -1
C is the correct answer I think
Answer: −
2
±
√
13
Step-by-step explanation:
(-b±√(b²-4ac))/(2a)
Plug in and solve.
Each student collects $1 per week.
There are 24 students, so combined, they collect $24 per week.
The time irt takes to collect $1500 is
$1500/$24 = 62.5
Answer 62.5 weeks, or if you need a whole number, 63 weeks.
