let length of the rectangle be l
length is 6 cm longer than the width, w
l = w + 6
perimeter of rectangle is 72 cm
= 2l + 2w
substitute l = w + 6
2(w+6) + 2w = 72
4w + 12 = 72
4w = 60
x = 15
ans is C. 15 cm
Answer is B let me know if you need to know why i will explain in comments
Equation for a circle
r^2 = (x - h)^2 + (y - k)^2
where r = sqrt[ (-2 - (-10))^2 + (-5 - (-20))^2]
sqrt[ (8)^2 + (15)^2 ]
sqrt[ 64 + 225 ]
= sqrt[289] = 17
equation for a circle
17^2 = (x - (-2))^2 + (y - (-5))^2
17^2 = (x + 2)^2 + (y + 5)^2
