The total cost to put the fence around the rectangular garden is $(2x - 2)
Step-by-step explanation:
Perimeter of the rectangular garden = 2[(3x - 5) +2x]
= 2(5x - 5) ft.
Total cost = 2(5x - 5) /5
=$ 2x - 2
The cost for putting the fence around the rectangular garden is $ (2x - 2)
x^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
