Answer:

(-mn + 10m + 5n)

Step-by-step explanation:

We have to subtract (15 mn- 22 m + 2n) from ( 14 mn - 12 m + 7n )

(14mn - 12m + 7n) - (15mn - 22 m + 2n)

When open the parenthesis before which a negative sign is given negative sign changes all signs of each term inside.

14mn - 12m + 7n - 15mn + 22m -2m

Now we add and subtract like terms.

(-15mn + 14mn) + (22m - 12m) + ( 7n - 2n )

(-mn + 10m + 5n)

So the answer is (-mn + 10m + 5n)

Identify all polar coordinates of (2, 0°). Please include all steps. Thanks.

(2, 0°) is already in polar coordinates, with the smallest possible angle. The radius is 2, always 2. Expressions with variations of the angle are also good representations of (2, 0°) if their angles are all integer multiples of 360 degrees. For example: (2, 720°) represents the same point in polar coordinates as does (2, 0°).
