The equation (x+5)^2 + (y+7)^2=81 is a variation of a circles standard formula (x - h)^2 + (y - k)^2 = r^2

The center of the circle is found by (h, k)

In this case:

h = -5

k = -7

Therefore the center is:

(-5, -7)

Hope this helped!

Which expression is equivalent to the expression below?(6c^2+3c/-4c+2)/(2c+1/4c-2)
algol [13]

Answer:

-3c

Step-by-step explanation:

The given expression is:

\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}}

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}} \\\\ =\frac{6c^{2}+3c}{-4c+2} \times \frac{4c-2}{2c+1}\\\\=\frac{3c(2c+1)}{-(4c-2)} \times \frac{4c-2}{2c+1}\\\\ =-3c

Thus, the given expression in simplified form is equal to -3c
