The equation of circle A is (x-4)2+(y-2)2=16 and the equation of circle B is (x+6)2+(y+3)2=9. what is the distance between the centers of these circles?
the equation of circle P is (x-3)2+(y+2)2=34 and equation of circle Q is (x-4)2+(y+5)=52 What is the distance between the centers of these circles?
And Use the distance formula to find the distance between the 2 centers. But I dont understand how.
its the square root of (x2-x) to the second + (y2-y)to the second. HELP!!!
