So for this question you need to look at what changed and what caused the change. the question states that the only real difference between when the flock of birds came and when they didn’t come was the loud eagle call (not any other loud animal), so it can be inferred that the eagle call scared the flock of birds away. so the answer is most likely c. hope this helps!!
If you round 4.309 you get 4.31 which is .08 less than 4.39.
X^2 + 9x + 8 = 0
To find the factors we need to find two number that multiply to equal 8 but add to equal 9.
8 = 1*8 9 = 1+8
(x + 1)*(x + 8) = 0
(x² + 4x - 45)/(x² + 10x + 9)
<span>
Numerator = N = x² + 4x - 45 </span>
= x² + 9x - 5x - 45
= (x² + 9x) - (5x + 45)
= x(x + 9) - 5(x + 9)
= (x + 9)(x - 5)
<span>
Denominator = D = x² + 10x + 9 </span>
= x² + x + 9x + 9
= (x² + x) + (9x + 9)
= x(x + 1) + 9(x + 1)
= (x + 1)(x + 9)
<span>
Hence, the given expr. = N/D </span>
= {(x + 9)(x - 5)}/{(x + 1)(x + 9)
= (x - 5)/(x + 1)
<span>
Restrictions : x ≠ - 1, x = 5 </span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
