the answer is zero exstranues solutions
<u>Answer</u>
0
<u>Explanation</u>
9/(n²+1)=(n+3)/4
9/(n²+1) = (n+3)/4
(9 × 4)/(n²+1) = n+3
36/(n² + 1) = (n + 3)
36 = (n²+1)(n+3)
36 = n³+3n²+n+3
n³ + 3n² + n - 33 = 0
This is a cubic function and so, it have 3 solutions.
No extraneous solutions.
Answer
112 Adam's book
Answer:
Population in 1950 was 4,100,000
Step-by-step explanation:
Equation: 5x + 2,000,000 = 22,500,000
Subtract 2,000,000 from each side: 5x = 20,500,000
Divide each side by 5: x = 4,100,000
