I would like a better Understanding on how to complete the following, please explain. Find the work done by the force F in moving an object from P to Q.
F = 300i + 60j; P(−1, 1), Q(200, 1)

50- 250 is correct i did that one too

step-by-step explanation:

i would say true? if the unit was informational and it "refreshed your understanding", then true.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
