Answer:
45
Step-by-step explanation:
Decreasing by 25% means that there is 25% less of last years amount or 0.25x less. It also means that this year there is only 75% of what was last year actually in the lake or 0.75x. Since last year, there were 60 fish, this means this year there is 0.75(60) = 45. This year has 45 fish.

Answer:
D
Step-by-step explanation:
Given
x² + 6x - 9 = 0 (add 9 to both sides )
x² + 6x = 9
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 9 + 9
(x + 3)² = 18 ( take the square root of both sides )
x + 3 = ± 
= ± 
= ± 3
Subtract 3 from both sides
x = - 3 ± 3 → D
