the area of a square sandbox is 83 square feet. to the nearest foot, what is the perimeter of sandbox?

vagabundo [1.1K]

$Area=bh$
$b=base$
$h=height$

Since a square has 4 equal sides, we can √83 to give us each side. This being $9.11 feet$

$perimeter=9.11+9.11+9.11+9.11=36.44$

$Answer: 36$ to the nearest foot

A circle has the equation x^2−8y−6x+y^2=4.

mylen [45]

Hello here is a solution :
x²-8y-6x+y²=4....(1)
A)
x²-6x = x²-2(3)x+9-9
= x²-2(3)x+3²-9
x²-6x =(x-3)² -9
B)
y²-8y = y²-2(4)y +4²-16
y²-8y = (y-4)²-16
C)
in (1) :

(x-3)² -9 +(y-4)²-16 = 4
(x-3)² +(y-4)² = 29 ...is the standard form of the equation

 Select answer 1 :
A: 3
B: 4
C: (x−3)2+(y−4)2=29
