Answer:
C (3,10) center and radius 3
Step-by-step explanation:
The equation of a circle can be written in the form
(x - h)² + (y– k)² =r²
where (h,k) is the center and r is the radius
Given
(x - 8)² + (y– 10)² = 9
Rewriting
(x - 8)² + (y– 10)² = 3²
We know that
(8,10) is the center and 3 is the radius
Hello!
Your answer is: 9x
because you are subtracting a negative, invert the symbols
(7x) + (2x)
then just combine the like terms to get 9x
I hope this helps, and have a nice day!

Answer: 2*2*2*2*5</h3>
We have four copies of '2' and one copy of '5' multiplied together
This is the same as saying 2^4*5
=========================================
Explanation:
Divide 80 over the smallest prime factor, which is 2
80/2 = 40
Divide that result over 2
40/2 = 20
Keep going until you cannot divide by 2 anymore
20/2 = 10
10/2 = 5
We stop here because 5/2 isn't a whole number. We also stop here since 5 is prime. Circle all the primes that show up and you should have four copies of 2 and one copy of 5.
Therefore: 2*2*2*2*5 = 80
In shorthand, this condenses to 2^4*5 = 80
The factor tree is shown below. Other factor trees are possible.
Both rays and lines continue forever, therefore, a lime segment is the only choice that works.
