Answer:
B:5x
Step-by-step explanation:
It would be B because if you add all the sides together you would get 5x and 5x is B
8/1/2=10/n=2*(n-15)/3n*3n=0*3n. Now we do, 2*(n-15)=0, which gives us 2=0. N-15=0. So n=15. Therefore, the answer is n=15.
The uncertainty in x is the horizontal width of the rectangular marker, which is 0.05 mm.
The uncertainty in y is the height of the rectangular marker, which is 0.1 g.
