So first you factor it out:
8c - 72 = 12c - 72 - 4c
Then you isolate the c's:
-72 +72 = 12c - 4c -8c
Then you add both sides:
0 = 0c
C is equal to 0
Answer:
Okay so I am assuming you mean the third part?
Step-by-step explanation:
Pretty simple. So you see that the varible x^2 does not have a number in front of it, so there is no extra dividing.
A formula for a perfect square is (x^2)+2xy+y^2
Take 10 and divide it by 2.
10/2=5
You have Y. Finding the third part is squaring Y.
5^2=25
Therefore, the third part of the perfect square is 25. If you want to find Y, look at the stuff above.
The explicit formula of an arithmetic sequence:
We have:
Substitute:
Answer: an = 30n - 130
