Answer:
60
Step-by-step explanation:
First, find the area of the square as it the missing piece wasn't missing.
8 x 9 = 72
Then, find the area of the missing section.
3 x 4 = 12
Finally, subtract 12
from 72
and you get 60
The answer is B. To find the Circumference (what you're looking for) you use 2×pi×radius. Which is 2×pi×7. In terms of pi that's just 2×7, which equals 14. So that means your answer is 14pi.
Answer:
True
Step-by-step explanation:
First, we need to recognize that

Now, we can try to solve

Multiply each side by 

As we end up with an answer that cannot be true, we know that there is no solution.
Another method to solve this would be graphing the function 
When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.
