Answer:
20
Step-by-step explanation:
Let A, B, C and D sets.
Let |A| the number of elements of A.
Remember, the quantity of elements that have the set
is

1. Since each set has 100 elements,
2. each pair of the sets shares 50 elements
3. each three of the sets share 25 elements,
4. the four sets share 5 elements
Then

So, there are 20 elements in the union of the sets A, B, C and D
I know the answer is that Princeton scores 15 goals but I don’t know how the work is supposed to be shown. I did it in my head. I multiplied both 8 and 5 by 3 so 8 would become 24(the goals Rutgers scored) and then you would find the number of goals Princeton scored. Sorry I couldn’t show the work but the answer is 15 goals.
Option b:
is the correct answer.
Explanation:
The expression is ![\log _{w}\left(\frac{\left(x^{2}-6\right)^{4}}{\sqrt[3]{x^{2}+8}}\right)](https://tex.z-dn.net/?f=%5Clog%20_%7Bw%7D%5Cleft%28%5Cfrac%7B%5Cleft%28x%5E%7B2%7D-6%5Cright%29%5E%7B4%7D%7D%7B%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%2B8%7D%7D%5Cright%29)
Applying log rule,
, we get,
![\log _{w}\left(\left(x^{2}-6\right)^{4}\right)-\log _{w}(\sqrt[3]{x^{2}+8})](https://tex.z-dn.net/?f=%5Clog%20_%7Bw%7D%5Cleft%28%5Cleft%28x%5E%7B2%7D-6%5Cright%29%5E%7B4%7D%5Cright%29-%5Clog%20_%7Bw%7D%28%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%2B8%7D%29)
Again applying the log rule,
, we get,
![4 \log _{w}\left(x^{2}-6\right)-\log _{w}(\sqrt[3]{x^{2}+8})](https://tex.z-dn.net/?f=4%20%5Clog%20_%7Bw%7D%5Cleft%28x%5E%7B2%7D-6%5Cright%29-%5Clog%20_%7Bw%7D%28%5Csqrt%5B3%5D%7Bx%5E%7B2%7D%2B8%7D%29)
The cube root can be written as,

Applying the log rule,
, we have,

Thus, the expression which is equivalent to
is 
Hence, Option b is the correct answer.
Answer:
Step-by-step explanation:
9/16=x/12
cross product
16x=9*12
16x=108
x=108/16
simplify
x=27/4
---------------
x-3/18=12/9
x=12/9+3/18
x=24/18+3/18
x=27/18
x=3/2
--------------------
7/11=18/x+1
18/x=7/11-1
18/x=7/11-11/11
18/x=-4/11
x=18/(-4/11)=(18/1)(-11/4)=-198/4=-99/2
x=-99/2
