Answer + Step-by-step explanation:

your question is about equation 4 :

$b_{1}=14-b_{2}$

Then

$\left( b_{1}\right)^{2} =\left( 14-b_{2}\right)^{2} \ \text{(this is a special product )}$

Then

$\left( b_{1}\right)^{2} =14^{2}-2\times 14 \times b_{2}+ (b_2)^2$

Then

$\left( b_{1}\right)^{2} =196-28 b_{2}+ (b_2)^2$

which of the following equations correctly represents a circle centered at the origin with a radius of 5

yuradex [85]

Answer:

x² + y² = 25

Step-by-step explanation:

The standard form of a circle is (x - h)² + (y - k)² = r² where (h, k) is the center point and r is the radius. In this case, the center is the origin which has coordinates of (0, 0) so h = 0 and k = 0. We know that the radius is 5 so r = 5. Therefore, after plugging in the values of h, k, and r, we get that the answer is x² + y² = 25.
