Step-by-step explanation:
We want to the equation in an exact form
M(x, y) dx + N(x, y) dy = 0.
xy² dy/dx = y³− x³
Cross multiply
Then,
xy²dy=(y³-x³)dx
xy²dy - (y³-x³)dx = 0
xy²dy + (x³-y³)dx=0
Therefore,
(x³-y³)dx + xy²dy=0
Can only be an exact equation if and only if
dM/dy=dN/dx
From the equation
M=(x³-y³)
Then, dM/dy=-3y²
Also, N=xy²
dN/dx=y²
Since dM/dy ≠ dN/dx
Then it is not an examct equation and we can say
M≠(x³-y³)
And
N≠(xy²)

If 2 movie tickets cost $15, you can multiply that by 2 to get the cost of 4 movie tickets.
Answer:
The elapsed time is 7hrs and 1 minute.
The answer is A. multilpy 12×24 to get 288.subtract 24 from 32 to get 8, which is the leng th of the triangle. 12×8=96÷2=48. 48+288=336
