Do parenthesis first (4)
Then, do the division 8/2 = 4
Then multiply 4 and 4 which will be 16
Add 6 to 16 and you get 22
1/40 would be your answer because 0.025 is would be 25/1000. Simplify that then you would get 1/40.
Hello :
PA = PB or PA² = PB²
(5-b)²+(4-2)² = (2-b)² + (5-2)²
(5-b)²+4 = (2-b)² + 9
25 -10b +b² + 4 = 4 -4b+b² +9
-6b = -16
b = 8/3
Answer:
20.8
Step-by-step explanation:
The first step you need to do is to subtract 11:

Mark was thinking of 20.8
Answer:
C
Step-by-step explanation:
The area (A) of a regular decagon is
A = 
perimeter × apothem
perimeter = 10 × 8 = 80 in, thus
A = 0.5 × 80 × 12.3 = 492 in² → D
