Answer:
-39
Step-by-step explanation:
Substitute x by - 3 and y by 4
(-3)^3 - 3 *4 = - 39
I think this mean that in whatever equation you have, w must be representing -3. Not sure though :)
Use PEMDAS
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)

Add all the displacement vectors together, then find the magnitude of this vector sum.



Summing these vectors gives the resultant displacement

and we have

so the plane ends up about 81.9 km away from its starting position.
