Hey there!

We can first factor out the 4 (bring it outside the parenthesis)

Now have a closer look between the parenthesis, because this expression can be factored as well. We're looking for two different numbers with a product of -6 and a sum of 5. Hence, we find the numbers 6 and -1

Answer:
x^2 + y^2 = 25
Step-by-step explanation:
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can see that the center is (0, 0) by looking at the graph, and the radius is 5 because it is marked. Plugging these in we get:
x^2 + y^2 = 25
Answer:
The equation is already in simplest form.
Step-by-step explanation:
you cannot combine any of the numbers because they are not like terms, so it cannot be simplified further.
17.5
5 is the og length. Scale factor is 3.5. So
5(3.5)=17.5
