Answer: The elephant that will weigh
in Planet B.
A circle is a set of points in a plane equidistant
from a fixed point. It has a general formula of x² + y² = r². This is if the
center is at the origin. However, if the center at point h and k, the
equation becomes (x-h)² + (y-k)² = r².<span>
We write the given equation in the
form (x-h)² + (y-k)² = r² by completing the square.

<span>x</span>²<span> + y</span>²<span> + 10x – 6y + 18 = 0</span>
<span>
(x² + 10x + 25 )+ (y² - 6y + 9) = −18 + 25 + 9 = 16
(x + 5)² + (y + 3)² = (4)²
Therefore,
center = (-5, -5)
radius = 4</span>
Answer:
13.27 cm
Step-by-step explanation:
The hypotenuse is always the longest side so:
a^2 + 20^2 = 24^2
a^2 + 400 = 576
a^2 = 176
a = 13.27
