Answer:

<h2><u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u></h2>

Step-by-step explanation:

Write an expression for the perimeter of a rectangle with a length of

(3x² + x + 2) and a width of (-x² – 5x + 1).

P = 2 × (L + W)

<u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u>

if you want the result:

4x²−8x+6

Question 6 (Essay Worth 2 points)<br> Find all polar coordinates of point P = (2, 14°).
andrey2020 [161]

Answer:

(2,14°+360n) and (-2,14°+(2n+1)180°)

Step-by-step explanation:

You start out with (2, 14°)

The polar coordinate can be written as (r, 0) = (r, 0+2nπ) or

(r,0)=(-r,0+2(n=1)π), where n is any integer.

The polar coordinates point : p=(r,0) = (2,14°)

For the positive value of r,  the polar coordinate can be written as

p=(2,14°) = (2,14°+360n°), where n is any integer.

For the negative value of r ,  the polar coordinate can be written as

p=(2,14°) = (-2,14°+(2n+1)180°), where n is any integer.

All the polar coordinates of point P are(2,14°+360n) and (-2,14°+(2n+1)180°).

The negative in front of the second bracket means that it's times by -1 so each of their signs switches: 
3m^2+2n-m^2-2n 
Add like terms 
2m^2 
the 2n cancels out
