The constant that can be added to 
- 3x to form a perfect square trinomial is 
The given expression is
- 3x
To form a perfect square trinomial
The given expression is
- 3x
first we have to add a constant term with it
- 3x + z
By comparing the given expression and the perfect square trinomial
a = x
Similarly
-2ab = 3x
where know a =x
Then,
-2b = 3
b = -3/2
Similarly
= z
9/4 = z
Convert the simple fraction to mixed fraction
9/4 =
Hence, the constant that can be added to - 3x to form a perfect square trinomial is
The complete question is :

We need to know the amount of food and spoiled food and each customer
To find the total number of butterflies we add 9 and 7, which equals 16 butterflies in all. Then we take the queen butterfly part of the ratio, which is 7 and compare it with the total number of butterflies to get the ratio 7:16.
Answer:
r=2
Step-by-step explanation:
y = k x^r is the formula for a direct variation
y = k x^ -r is the formula for a indirect variation
20= 5 (1/2)^ -r
Divide each side by 5
4 = (1/2) ^ -r
Rewriting
2^2 = 2^ -1 ^ -r
2^2 = 2 ^ r
The bases are the same so
2 =r
