Answer:
A and E
Step-by-step explanation:
because b is 13 c is 12 and d is -54
75 m = 0.75 m
<span>251 km = 251,000 m
</span>0.46 cm = 4.6 mm
58 mm = 0.058 m
In your problems that ask the position of the ant labeled as B if they are crawling in a straight wire which shall call the x axis form a to b to c to d the answer to you problem base on my calculation and by understanding the best answer would be 59cm
