Step-by-step explanation:
20 + 37 = 57in
Answer:
Step-by-step explanation:
let x and y be the sides of the rectangle.
2(x+y)=44
x+y=44/2=22
y=22-x
1 tile=1 sq. ft.
120 tiles=120 sq.ft.
area=120 sq.ft.
xy=120
x(22-x)=120
22x-x²=120
x²-22x+120=0
x²-12x-10x+120=0
x(x-12)-10(x-12)=0
(x-12)(x-10)=0
x=12,10
if x=12
y=22-12=10
if x=10
y=22-10=12
floor dimensions are 12 ft ×10 ft
The equation of a circle is:
(x - h)² + (y - k)² = radius²
where (h, k) is the center of the circle.
Your center is (- 2, - 7).
Your radius is √81 = 9
