To fence a rectangular garden, we need to fence the length 2 times, and the width 2 times.
So, it will take 120 : 2 = 60 meters of fence to fence 1 length and 1 width
-> The length = 60 : (3+1)x3 = 45 (meters)
-> The width = 60 - 45 = 15 (meters)
Recheck : (45+15) x 2 = 120 and 45:15 = 3
(If it's wrong you can tell me, I don't really know what do you mean by how wide is the fence)
Answer:
d) (x -2)² +(y +5)² = 256
Step-by-step explanation:
For center (h, k) and radius r, the standard equation of a circle is ...
(x -h)² +(y -k)² = r²
For (h, k) = (2, -5) and r = 16, we can fill in the numbers:
(x -2)² +(y -(-5))² = 16²
(x -2)² +(y +5)² = 256 . . . . simplify
(x + 1) (x + 2)
x² + 2x + x + 2
so your answer is:
x² + 3x + 2
