Okay so
If there are 28 white ducks, and twice as many brown ducks thats
28x2=56
So the total amount of ducks is 56(brown)+28(white)=84
Then, if half the amount of while ducks fly away thats
84-14=70 (You get 14 by diving the amount of white ducks by 2 28/2=14)
Therefore, there are 70 ducks in the pond after half the amount of white duckies fly away.

13.
A.) 2(4)^2 - 11 = 21. B.) 2(-4)^2 - 11 = 21
* Note: if the power is a even number (2, 4, 6, and on), then the negative won't affect the answer and can be forgotten.
14.
A.)2squareroot16 - 10 = -2.
B.)2squareroot16 - 10 = 14
15.
|-3 - 8| + (-3) =8
|1/2 - 8| + 1/2 = 8
