The result of the given expression on simplification is -3
<h3>Solving expressions</h3>
Polynomials are expressions that has a leading degree of 3. Given the expression below;
x^2-x^3+x^2/-x^2
Simplify the numerator to have:
2x^2-x^2/-x^2
Factor out x^2 from the numerator
-x^2(2+ 1)/-x^2
-3x^2/-x^2
Cancel out x^2 to have;
-3x^2/-x^2 = -3
Hence the result of the given expression on simplification is -3

The guy above me got it right
Answer:
x is horizontal, at the bottom(left to right), and y is vertical, going up and down
Step-by-step explanation:
see above
For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:
With the wind against the speed is:
Rewriting both equations, we have the following system of equations:
Then, solving the system of equations (graphically for example), we have the solution is:
Therefore, jet stream's speed:
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
