It is 5 because you have to multiply by 5 by 4 and get 20 when you multiply by 5×1 and get 5

Step 1 = Distributive Property ( multiplying the 2 by each term in parenthesis)

Step 2 = Addition Property ( adding like terms)

Step 3 = Addition Property (adding 34x to each side)

Step 4 = Division Property. ( dividing both sides by 17)

Answer:

$(x-4)^2+(y+7)^2=43$

Step-by-step explanation:

The standard equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center and r is the radius.

We are given that the center is (4, -7) and that the radius is √(43).

So, h = 4, k = -7, and r = √(43). Substitute:

$(x-(4))^2+(y-(-7))^2=(\sqrt{43})^2$

Simplify. Hence, our equation is:

$(x-4)^2+(y+7)^2=43$
