<h3>Answer: Choice B</h3>
which is the same as x/((x+6)(x-2)) - 3(x-2)/((x+6)(x-2))
=====================================
Explanation:
The LCD is (x+6)(x-2) which is the factorization of x^2+4x-12, and that is the denominator of the first fraction. The first fraction has the LCD already. The second fraction does not. It has (x+6) but it is missing (x-2).
We multiply top and bottom of the second fraction by (x-2) to get the second fraction to have the LCD.
turns into
------
So,
This is the same as x/((x+6)(x-2)) - 3(x-2)/((x+6)(x-2))
Note the parenthesis around "(x+6)(x-2)"
Instead of x/(x+6)(x-2) you should write x/( (x+6)(x-2) ) to ensure that all of "(x+6)(x-2)" is in the denominator.
<u>Answer:</u>
Divergent
<u>Step-by-step explanation:</u>
We can make use of the exponent function to solve this question. The function would be like:
where is the first payment
,
= ratio of increase
; and
= the number of payments.
So it can be written as:
The series will keep increasing since the ratio of the function is 1.3 which was > 1 so. Therefore, the series is divergent.
