Answer:
equation;
Center (-4,2)
Radius is
Step-by-step explanation:
Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of
Where (h,k) is center
r is the radius
So first we group like Terms together
Add 7 to both sides
Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem
and
so we have
To find our center, h is -4 and k is 2
so the center is (-4,2)
The radius is
So the radius is 3 times sqr root of 3.

<h3>2/5 is your answer. </h3><h3>▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓</h3>
☞ First, 0.40 is the same as 40/100.
But we are not done.
<u>Now, doing this you need to find the GCF (Greatest common factor) of 40, 100.</u>
2 x 2 x 5 = 20.
☞ So our GCF is 20.
Divide both the numerator and the denominator by the GCF.
40 ÷ 20 / 100 ÷ 20.
<h2>Simplify to get ☞ 2/5.</h2><h2>▬▬ι══════════════ι▬▬</h2>
Best of luck on your assignment!
