Answer:
(x + 4)^2 + (y-9)^2 = 121
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k) ^2 = r^2 where (h,k) is the center and r is the radius
(x - -4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 121
You divid the top by the bottom and get 8.8571
Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft
The answer is C because if you convert it gives you 50
