An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.

3(x+1) = -2(x-1) + 6
3x + 3 = -2x + 2 + 6
5x + 3 = 8
5x = 5
x = 1
Answer:
6x^3-13x^2+16x+7
Step-by-step explanation:
(3x+1)(2x^2-5x+7)
6x^3-15x^2+21x+2x^2-5x+7
6x^3-15x^2+2x^2+21x-5x+7
6x^3-13x^2+16x+7
