Domain goes from left to right. I know that it cant be C or D. My answer is B.
There are a couple of different approaches you can use for this. Here's one.
1. Determine how many digits repeat. (There is just one repeating digit.)
2. Call your number x. Multiply x by 10 to the power of the number of digits found in step 1.

3. Subtract the original number, then solve for x.

_____
If you recognize that 0.333... (repeating) is 1/3, then you know that 0.0333... (repeating) is 1/10×1/3 = 1/30. Add that to 0.8 = 4/5 and you get
... 4/5 + 1/30 = 24/30 + 1/30 = 25/30 = 5/6
Answer:
8.2
Step-by-step explanation:
-7.2 to -7.2 is 0
-9.3 to -1.1 is 8.2
Pythagorean theorem is a^2+b^2=c^2
0^2=0
8.2^2=67.24
0+67.24=0
√67.24=8.2
The distance between the to points is 8.2
Hmmm...I don't know what to tell you I can't type out your answer For you.
