Gain - loss = profit
55- 45 = $10 net profit
ok so to start combine like terms in the problems meaning you combine the numbers that have the same variable like 7x and 3x etc.
Answer:
The required factors are: x, (x + 6) and (x - 3).
Step-by-step explanation:
As per the question,
The given polynomial is:

Now,
BY factorization, we get


By splitting the mid-term, that is split 3x like:
3x = 6x - 3x
Therefore,

Now on further solving by taking common factor out, we get
![=x[x(x+6)-3(x+6)]](https://tex.z-dn.net/?f=%3Dx%5Bx%28x%2B6%29-3%28x%2B6%29%5D)

Therefore, the given second polynomial (x - 4), is not a factor of given polynomial
.
Hence, the given polynomial has three factor x, (x + 6) and (x - 3).
If f(x) is some function with period T, then f(x) = f(x+T) for all x in the domain.
In this case, T = 5 is the period so
f(x) = f(x+5)
f(3) = 10
f(3) = f(3+5) = f(8) = 10
f(8) = f(8+5) = f(13) = 10
Therefore, f(13) = 10
The final answer is 10
