I don't know how you expand it but the answer is 3x + 25 unless that's expanding.
(2000 - 150) / 67
27
(3000 - 400) /6
434
(20 - 7) / .75

Answer:
If a desert became flooded, some species would immeadiately go extinct, distrupting the ecosystem, biodiversity, and the food web. This flood might cause new species to enter the ecosystem as well, through means such as rafting. Other species would be forced to adapt to the new environment, leading to adaptation and possibly speciation. For a time the ecosystem would not be very stable, but after a relatively short time, 10 or 20 years, the ecosystem could stabilize itself. So my conclusion is that ecosystems are relatively fluid, they can adapt to almost anything if they have enough time and the change in environment isn’t too drastic.
Step-by-step explanation:
7x^2 minus 10x^2 is 3x^2
-7x +9x is 2x
Lastly, 1 + -5 is -4
So your answer should be 3x^2 +2x-4. I hope this helps. Also I hope the picture is clear enough to see!
