so ar^ = 2000 and you told me r = 10
a(10^5) = 2000
a = 2000/100000 = 1/50
0.3333333333... = 1/3
You can just say 0.3 repeating to say 0.33333...
All I did was add all A's, B's, and C's separately. Than I added them all together and got 316 total surface area. I tried but I learned this sooo long ago so i'm sorry if you get it wrong. Good Luck!
Answer:
do the math
Step-by-step explanation:
The answer to your questions are......

B. 8........(8 + 7)(8 - 8) = 0
C. -7........(-7 + 7)(-7 - 8) = 0
2.
A. 1/3.......(3*1/3 - 1)(5*1/3 + 20) = 0
C. -4.......(3*-4 - 1)(5*-4 + 20) = 0
Hope this helps! :)
