Answer:
x^2 + y^2 = 25
Step-by-step explanation:
So the length will be 18^2-4^2 all rooted. 18 square is 324 and 4 square is 16 and 324-16 is 308 so the answer will be the root of 308 or 2 root 77, at least that is what I think.
√8 = √2^2 *2
√2^2 *2 = 2√2
Basically, because 8 equals (2 to the power of 2) times 2, when you find the square root, you can take the 2^2 out, since you're finding the square root of 2 squared.
Hope I kind of make sense.
