Answer:
If x2 + 6x + c = (x + d)2, then d =What value of c makes x2 + 6x + c a perfect square trinomial? c =
Divide the x-term coefficient by 2: 6/2 = 3
Now square 3: 3^2 = 9
c = 9
If x^2 + 6x + c = (x + d)^2, then d =
x^2 + 6x + 9 = (x + 3)^2 = (x + d)^2, so d = 3
Step-by-step explanation:

There are two different ways we can read your question.
Each way has a different answer.
Here it is both ways:
Way #1: (12 + 4n) / 3 = 8
Multiply each side by 3 : 12 + 4n = 24
Subtract 12 from each side: 4n = 12
Divide each side by 4: n = 3 .
====================================
Way #2: 12 + 4n/3 = 8
Subtract 12 from each side: 4n/3 = -4
Multiply each side by 3: 4n = -12
Divide each side by 4: n = - 3
The answer is 93
Hope that helps! :)
