Answer:
'A=(3,-1) 'B=(2,-4) 'C=(0,-1)
Step-by-step explanation:
I don't really know how to explain it
The answer to the question would be B which is 169.91 dollars
The perimeter of these can be found by adding length and width and then multiplying by two.
Rectangle A: (with all of the variables already doubled)
2x + 16 + 2x - 2
2x + 2x + 16 - 2
4x + 14
So rectangle A's perimeter is 4x + 14.
Rectangle B: (Still with all the variables already doubled)
8x + 10 + 6x - 4
8x + 6x + 10 - 4
14x + 6
So rectangle B's perimeter is 14x + 6
And now to subtract the two.
(7x + 3) - (4x + 14)
14x + 6 - 4x - 14
14x - 4x + 6 - 14
10x - 8
So it would be C.
That is 5*20 is 100 and the inverse of 5 is 25
From this picture you can calculate coordinates of triangles' vertices:
![A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)](https://tex.z-dn.net/?f=A%28-9%2C0%29%2C%5C%20B%28-6%2C-4%29%2C%5C%20C%28-3%2C0%29%2C%5C%20J%288%2C0%29%2C%5C%20G%285%2C4%29%2C%5C%20H%282%2C0%29%20)
.
Since
you can conclude that points A, B, C are rotated by
![180^0](https://tex.z-dn.net/?f=180%5E0)
about the point (-0.5,0) to form points J, G, H, respectively.
Answer: A is correct choice.
