2(7x+27)=180

14x+54=180; subtract 54 from both sides

14x=126; divide both sides by 14

x=9

Write an equation of the circle with center (-7,4) and radius 11.

olga_2 [115]

Answer: (x+7)^2 + (y-4)^2 = 121 or (x+7)^2 + (y-4)^2 = 11^2

Step-by-step explanation:

Equation of the circle is:

$(x-h)^2+(y-k)^2=r^2$ , which is the center $(h,k)$ and the radius $r^2$

-Place the center (-7,4) and radius 11 onto that equation:

$(x+7)^2+(y-4)^2=121$ (if simplified radius needed)

$(x+7)^2(y-4)^2=11^2$
