Answer:
None of these
Step-by-step explanation:
None of this expressions are equivalent. But if the original polynomial is 9x^2-4, then answer would be (3x+2)(3x-2).
Using formula (a+b)(a-b)=a^2-b^2 , it follows:
(3x+2)(3x-2)=(3x)^2-2^2=9x^2-4
Answer:

Answer:
75
Step-by-step explanation:
Since the ratio between flamingos and chachalacas is 2:1, we see that the ratio of flamingos to chachalacas to parrots to herons is 10:5:7:3. The sum of these numbers is 25, so every 'ratio number' gets 375/25 = 15 animals. So the number of chachalacas is 15 * 5 = 75.
