Answer: B
Step-by-step explanation:
Those lines around n mean it’s talking about absolute value. Absolute value is the positive version of any number. This that -1 would turn into 1. If that’s the case, then |n| < 0 would be false
The answer is 4pi because the formula to find the circumference is C = 2 pi r. this question is asking for the terms of pi which means you remove the pi from the formula and solve it with out it. the radius is 2 because of the 2 units on the graph is halfway of the circle. you would just multiply 2 x 2 and get 4. after that you put the pi on the end of the 4. so the answer is C. (4pi)
4 is the greasy common factor
W is equal to 19/4 or 4.75
Hope this helps! :)
I know for 2x you would go up 2 over 1 but I don’t know about -7?? Maybe down
