If the equation of a circle is (x+5)2+(x-7)2= 36, its radius is

6

Step-by-step explanation:

The equation for a circle is (x-h)^2 +(y-k)^2 = r^2

where (h,k) is the center of the circle and r is the radius

(x+5)^2+(y-7)^2= 36

Rewriting

(x+5)^2+(y-7)^2=6^2

The center is at (-5,7) and the radius is 6

the answer is d. 75%

the equivalent expression are always the hardest ones but you look at the gcf also
