Pleas the diagram to answer the question.

what is the equation of the circle?

x2+y2=25

x2+y2=5

x2+y2=√5

x2+y2=10

The equation for any circle centered at the origin with a radius r is the following:

By looking at the picture, we can see that the radius is 5. We can also use the distance formula to find the distance between (0,0) and (-3,-4), and we will also get 5.

Thus, r=5.

This makes the equation:

That should be your answer, let me know if this is confusing in any way.

Happy Studying~

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
