Answer: B/The second answer
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)
(x-4)/2(x+4)
Answer:
(f- g)(x) = x - 3
Step-by-step explanation:
(f- g)(x) = f(x) - g(x)
This means that you have to subtract the two equation.
If f(x) = 3x - 2 and g(x) = 2x + 1
Then
f(x) - g(x) = [3x - 2] - [2x+1]
= 3x - 2- 2x - 1
= x - 3
∴ (f- g)(x) = x - 3
Answer:
4137.5 per year
Step-by-step explanation:
what you would do is take the number for private college and divide it by 8 years since you only want one year and divide that by four since it says four years and that would be your answer
