Equation of the circle is : 
Step-by-step explanation:
Let us consider the image attached in the answer area.
The center<em> O</em> has the co-ordinates i.e. <em>(-5,2)</em> and the diameter given is <em>12 units</em>.
We know that radius is half of diameter.


The equation for circle given the center and radius, can be represented as:

Where <em>(a,b)</em> is the co-ordinate of center and <em>r</em> is the radius.
Let us consider the following formula:


Hence, Equation of the circle is : 
Answer:
B: x=-5 and x=4
Step-by-step explanation:
f(x)= x^2 + x -20
To find the zeros we replace f(x) with 0

now we solve for x
LEts factor x^2 + x -20
sum is +1 and product is -20
5 * (-4)= -20
5 + (-4) = +1
x^2 + 5x - 4x - 20 = 0
(x^2 + 5x)+(- 4x - 20) = 0
x(x+5) -4 (x+5) = 0
(x-4)(x+5)=0
Set each factor =0 and solve for x
x- 4 =0 so x=4
x+5 =0 so x=-5
x=-5 and x=4
Answer:
I'm guessing you are trying to say this is 25p29=10-169 If not let me know in comments and I'll change it! But here is the answer: 72750<em>p</em><em>-</em><em>1</em><em>6</em><em>9</em>
<em>Expla</em><em>ined</em><em>:</em>
25p*29=10 – 169
solve=
72750p-169
