The student does a work of 500 Newton meter on the box.
Step-by-step explanation:
Given,
Weight of box of books = force = 200 N
Distance the box is lifted = 2.5 m
Work done = Force * distance
Work done = 
Work done = 500 Newton-meter
Newton meter is same as Joule.
Work done = 500 Joules

Answer:
9m+6m^2n
Step-by-step explanation:
12mn-3mn=9mn
4m^2n+2m^2n=6m^2n
==> 9m+6m^2n
or rewrite as 3m(3+2mn)
Answer:
B<C
Step-by-step explanation:
-a is the opposite of a. Since a is a negative number, it will become positive and be bigger than b, which is negative.
c is a positive number, so the opposite will be negative and can not be bigger than c.
