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

Answer:
ok
Step-by-step explanation:
Answer:
The Total number of Professors = 48
Step-by-step explanation:
Given as,
The total number of Faculty = 136
And the Ratio of Professors to Lecturers = 6 Ratio 11
Now According to question
Professors : Lecturers = 6 : 11
So, Let the Number of Professors = 6x
And The Number of Lecturers = 11x
∴ 6x + 11x = 136
Or, 17x = 136
Or, x =
= 8
Hence, the number of Professors = 6 × 8 = 48 Answer
