Answer negative 9 is the answer
Step-by-step explanation:
C=8πab
Divide both sides by 8πb
c/(8πb) = a
2 + 2m = 6 equals
m = 2.
First, subtract 2 from both sides. Your problem should look like: 2m = 6 - 2.
Second, simplify 6 - 2 to get 4. Your problem should look like: 2m = 4.
Third, divide both sides by 2. Your problem should look like: m =
Fourth, simplify

to 2. Your problem should look like: m = 2, which is the answer.
Answer:
x = 18 or x = -12.
Step-by-step explanation:
||x-3|-5| = 10 only if |x-3|-5 = 10 or |x-3|-5 = -10, i.e., if |x-3|=15 or |x-3|=-5; but |x-3| cannot be equal to -5, because |x-3| should be a non-negative value. Therefore, the first equation is true only if |x-3|=15. |x-3| = 15 only if x-3 = 15 or x-3 = -15, i.e., x = 18 or x = -12. We can verify this in the following way: ||18-3|-5|=||15|-5|=|10|=10 and ||-12-3|-5|=||-15|-5|=|15-5|=|10|=10. This verify that our solution is correct.
