Write and equation of the circle with center (7,-5) and radius of 6.

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

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2 is the standard form, with center (h, k) and radius r.

So our circle must have a center h = 7 and k = +5 The radius is 6 so r^2 = 36.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
