I dont think this can be factored
Answer:
n = 15
Step-by-step explanation:
6(1+n)=8n-3(n-7)
Distribute
6 +6n = 8n -3n +21
Combine like terms
6+6n = 5n +21
Subtract 5n from each side
6+6n-5n = 5n-5n +21
6 +n = 21
Subtract 6 from each side
6-6+n = 21-6
n = 15
Given that
and
, we can say the following:

Now, remember what happens if we have a negative square root: it becomes an imaginary number. We don't want this, so we want to make sure whatever is under a square root is greater than 0 (given we are talking about real numbers only).
Thus, let's set what is under both square roots to be greater than 0:


Since both of the square roots are in the same function, we want to take the union of the domains of the individual square roots to find the domain of the overall function.

Now, let's look back at the function entirely, which is:

Since
is on the bottom of the fraction, we must say that
, since the denominator can't equal 0. Thus, we must exclude
from the domain.
Thus, our answer is Choice C, or
.

X = 6 after distributing then adding 39 to both sides and then divide by 13
