-18 x 4 = -72
Step-by-step explanation:
a negative times a positive is a negative number.
The answer is a.
Point A and point B
Given that the distance between two lines in the measurement instrument is 0.01m, the maximum error should be 0.01m/2 = 0.005 m.
If you do a good work, the real measure is 1.20m +/- 0.005m, this is between 1.195 and 1.205.
