The area of the polygons compare to π in the way that as more angles and sides are added to a polygon the polygon becomes closer to a circle; the perimeter slowly changes to circumference. Π is used to find the area and circumference of a circle, so as polygons come closer to becoming circles π becomes more strongly associated to the polygon. You can even use π to find the approximate area of a circle if you use the same formula (as you would to find the area of a circle) on a polygon. Another way to go about it is like this…

You can find the area of a circle if you know the circle’s circumference by using these steps:

1. Divide the circumference by π to find the diameter of the circle.

2. Divide the diameter by 2 to find the radius of the circle.

3. Now that you have the radius you can use the formula Area= πr2 to find the area of the circle.

Answer:

B.(x-6)

Step-by-step explanation:

12/(x^2 - 11x+30) - 43/(x^2-6x)

12/((x - 5) (x - 6)) - 43/x(x-6) [Factoring the denominator]

Both have x-6 common in the denominator,

Solve 6/×-3 =x/3

Eduardwww [97]

Answer:

X = -3. non-extraneous

Step-by-step explanation:

The given equation is $\frac{6}{x-3} =\frac{x}{3}$

We cross multiply to get:

$6*3=x(x-3)$

Expand and multiply.

$18=x^2-3x$

$x^2-3x-18=0$

We factor to obtain:

$(x-6)(x+3)=0$

$x=-3,x=6$

Checking for extraneous solutions

Substitute x=-3 $\frac{6}{-3-3} =\frac{-3}{3}$

$\frac{6}{-6} =\frac{-3}{3}$

$-1=-1$

$1=1$ .....Non-extraneous

Checking for x=6

$\frac{6}{6-3} =\frac{6}{3}$

$\frac{6}{3} =\frac{6}{3}$

$2=2$ ....Non-extraneous

1) oranges cost 1.00. How much will 5 dozen oranges cost?

RoseWind [281]

1) In a dozen, there are 12. Since there are 5 dozen, you would multiply 12 by 5, which is 60.
So 5 dozen oranges would cost $60.
2) For this, I'm guessing you need a ratio. So, 2 : 5 for white: blue. When can put that down to 1 white. 1: 2.5. The question (I'm unsure of) is asking ?: 8.5. 8.5÷ 2.5 = 3.4. So you'll multiply the white side as well, 1×3.4=3.4. So 3.4.
3) You need to find what one juice box would cost. So since there were 12 in the pack, you divide the cost by 12.
5.40÷12= .45
Now they are asking for an eighteen pack, so multiply what one would cost by 18.
.45×18= 8.1
It would cost $8.10.
