Let say x = -(-2) where x is the distance of number on number line from 0.
x = -(-2)
x = +2.
Since +2 is positive quantity, positive quantities are written to the right of 0 on number line.
Hence it is 2 units to the right of 0.
Answer:
the answer should be b but its the answer
Because it is a square all sides are equal so all sides are 20.25 because half of 81 is 40.5 and half of that is 20.25.
It is D) 14 Units because it takes seven units to get from -7 to zero and 7 units to get from 0 to 7. there fore 7+7=14.
