We know that
the equation of a circle is
(x-h+(y-k)²=r²
where (k,k)----> is the center
and
r----> is the radius
y²+2x+x²-24y= -120
Group
terms that contain the same variable
(y²-24y)+(x²+2x)=-120
Complete
the square twice. Remember to balance the equation by adding the same constants
to each side
(y²-24y+144)+(x²+2x+1)=-120+144+1
<span>Rewrite as perfect squares</span>
(y-12)²+(x+1)²=25
(x+1)²+(y-12)²=5²
the answer isthe coordinates of the center are (-1,12)the radius is 5 units
Because all sides of a square are equal. Regular polygons always have equal sides.
Answer:
Its the last one
Step-by-step explanation:
The two triangles are the same, but with different names therefore they are congruent
To get the answer to 1 you would subtract 11 from 14.75 and get 3.75. You then divide that number by 3 to get 1.25. Each topping costs 1.25.
