Answer:

20\ ducklings

Step-by-step explanation:

Let

x------> the number of ducklings

y------> the number of adult ducks

we know that

x+y=24 ------> equation A

\frac{x}{y}=\frac{5}{1}

so

x=5y

y=0.20x ------> equation B

Substitute equation B in equation A

x+0.20x=24

1.20x=24

x=20\ ducklings

Answer:

I am going to show you the first steps to complete squares for the given equation: 1) Starting equation: 3x^2 + 9x -4 = 0 2) Add 4 to both sides => 3x^2 + 9x - 4 + 4 = 4 => 3x^2 + 9x = 4 3) Extract common factor 3 in the left side => 3 (x^2 + 3x). Now, compare with a(x^2 + 3x) and you get a = 3. Answer: a = 3.
