(1) You can see that the 6 is being added to both sides.
You are trying to make both sides equal by adding 6, so it would be the Addition Property of Equality.
(2) 4 is being divided into both sides.
It would be the Division Property of Inequality. (you are dividing by 4 to make both sides equal)
"B" is the answer.
I hope this helps!

I believe the proper way to find the surface area of a sphere is 4 times 3.14 (which is Pi) times the radius squared. Or 4(3.14)*r^2.
Where I found 804.25
Answer:C
Step-by-step explanation:
180-(60+40)=80°
C=80°
20/sin80. =a/sin40
a=(20sin40)÷sin80
=13.1
