Answer:
<h2>A. (0, 4)</h2>
Step-by-step explanation:
The equation of a circle:

(h, k) - center
r - radius
We have the equation:

h = 0, k = 4, r = 5
If you need it rounded, it would be 2 then 20 then 76.1. If you just need the base numbers, it would be 1 then 19 then 76.7
Frist 5 in / 1 over 2 = 2.5
So yes she can do that
Answer: 9w+9
Step-by-step explanation:
First combine like terms: 6w+3w
You can't combine 9 and 9w so that would be your answer.
Then if it calls for it, use the commutitive property to move 9w before 9.
Hope this helps!
