Step-by-step explanation:
I got it right :)
The equation of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius.
To find the radius, we would find the square root of 144, which is 12.
r=12

Answer:
The equation has a maximum value with a y-coordinate of -21.
Step-by-step explanation:
Given

Required
The true statement about the extreme value
First, write out the leading coefficient

means that the function would be a downward parabola;
Downward parabola always have their vertex on top of the parabola and as such, the function has a maximum value.
The maximum value is:

Where:

So, we have:



Substitute
in 


<em>Hence, the maximum is -21.</em>
Answer:
The value of x for the given expression is 5 .
Step-by-step explanation:
Given expression as
+
= 
Now, arrange the equation
So,
=
- 
<u>Taking L.C.M on right hand side </u>
Or,
=
Or,
=
Or, x = 
∴ x = 5
So, The value of x = 5
Hence,The value of x for the given expression is 5 . Answer
