Step-by-step explanation:
In order to solve the given exercise, you can follow these steps:
1. Given the following function f(x):

You must substitute
into the function f(x). Then:

2. Evaluating, you get:

3. Now, the next step is to substitute
into the function g(x):

4. Finally, evaluating, you get the following result:

You can identify that it matches with the Option C.
Answer:
-2
Step-by-step explanation:
if x=- 2 then f(x)=(-2-5)3(-2+2)=0
so x=-2 is correct
31 i hope u got it right !!
N = d - 5
2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3
Let's see if it checks out.
n = 3
d = 8
2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.
