Start with x^2 + y^2 = r^2, where r signifies radius. Subst. 0 for x and 9 for y:
0^2 + 9^2 = r^2. Therefore, r = 9.
The std eqn is x^2 + y^2 = 9^2. this is a special case of
(x-h)^2 + (y-k)^2 = r^2 and is appropriate because the origin is at (0,0).
Answer:

Step-by-step explanation:
Answer:
your answer is the last option
Step-by-step explanation:
There is no way to prove what the length for line WU is. You can find the side lengths for VW and VU but not WU. Therefore the last option is the correct answer
X= -4
Y= 8
I would do an explanation but there’s too many parts and it’s very long and most likely complicated to understand also, but yeah
Answer:
3a^2+12a
Step-by-step explanation:
3a(4+a)
3a*4=12a
3a*a= 3a^2
