Answer:
solution for n is 
Step-by-step explanation:
Given an equation containing one variable n.
The equation is as follows:

To solve for n we can subtract 3/4 from both the sides
The result is

Verify:
Substitute the answer in the given equation.

Both sides equal thus proving our correctness of answer.
96 people. With every round, the number of people doubles. 3 turns into 6, which turns into 12, which turns into 24, which turns into 48, which turns into 96. The process is repeated only 5 times, but keep in mind when 3 people are chosen, it ends the first round. Hope this helps!!!

Answer:
8.216 put a line on top of the six because it's repeating
Step-by-step explanation:
A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.
The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x. Our c is 100 and our b is 20; we want factors of 100 that sum to 20. 10*10=100 and 10+10=20, so those are what we need. This gives us (x+10)(x+10 for the factored form.
Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10). Using the distributive property we have 4*x+4*10=4x+40.
To find the perimeter when x=4, substitute 4 into our perimeter expression:
4*4+40=16+40=56.
The equation was just flipped around, it will equal the same no matter what.
I hope this helps!! :)
