yeah. in this case and shape it's rather obvious.

but furthermore the sum of all angles are 360°!

I need help with this,, will give brianliest and +15 points

Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

= 6x²+6x+3x+3+3x²-2x+8

= 9x²+7x+11

Difference:

(50x²-9x²)+(-34x+7x)+(38-11)

= 41x² - 27x + 27

Point a is at (-7,-7) and m is at (-6,-1) what are the coordinates of point b

AlekseyPX

Answer:

The coordinates of point b are (-5,5).

Step-by-step explanation:

Given:

Point a is at (-7,-7) and m is at (-6,-1).

So, to find the coordinates of point b.

Let a (-7,-7) be $(x_{1},y_{1})$ , m (-6,-1) and b $(x_{2} ,y_{2})$ .

Now, putting the formula to get the coordinates:

$m=\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}$

⇒ $(-6,-1)=\frac{-7+x_{2}}{2} , \frac{-7+y_{2}}{2}$

So, here we will make two equations to find the value of $x_{2} andy_{2}$ :

$-6=\frac{-7+x_{2}}{2}$

multiplying both sides by 2

⇒ $-12=-7+x_{2}$

⇒ $-5=x_{2}$

And, now same method for getting the value of $y_{2}$ .

$-1=\frac{-7+y_{2}}{2}$

multiplying both sides by 2

⇒ $-2=-7+y_{2}$

⇒ $5=y_{2}$ .

The value of $(x_{2} ,y_{2})$ = $(-5,5)$ .

Therefore, the coordinates of point b are (-5,5).
