55 Tiles are needed to cover 41.25 in.
B. because it only has one number before the decimal
Step-by-step explanation:
x² + 12x + y² - 8y = 73
(x² + 12x + 36) + (y² - 8y + 16) = 73 + 36 + 16
(x + 6)² + (y - 4)² = 125.
Hence the coordinates of the center is (-6, 4).
Since (16 + 6)² + (-1 - 4)² = 22² + (-5)² = 509 and 509 is not equal to 125, (16, -1) does not lie on the circle.

Answer:
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
