Option B is the correct answer.
3 is greater than -5, -9, and -1.
Hint: Remember to distribute the negative when solving. A negative directly outside outside of and to the left the parenthesis times a negative number inside the parenthesis makes that number positive.
So for option B, you can simplify it to -3 +4 +2. And that equals 3.
A) -3+-4-(-2) = -5
B) -3-(-4)-(-2) = 3
C) -3+(-4)-2 = -9
D) -3-(-4)-2 = -1
The sum of the interior angles of a hexagon is 720 degrees. If 3 angles are congruent, each with measure x degrees, and the other 3 angles are also congruent to each other, each with measure 2x degrees, then the total sum of all 6 angles would be 3x + 3(2x) = 9x. If this is equal to 720, then x = 80 degrees, while 2x = 160 degrees.
Therefore, there are 3 80-degree angles and 3 160-degree angles.

Answer:
Given - Radius of ring is 9 millimeters
To find - Circumference
Solution -
9 millimeters = 0.9 centimeters
Circumference of circle = 2 × pie × r
= 2 × 3.14 × 0.9
= 6.28 × 0.9
= 5.652
