You are right. In circle equation we have =r² so the correct answer will be C od D. But we have to calculate the center of a circle.

Complete the square:

And we have:

So the answer is C (the same left side of equation).
You first identify what supplementary angles are,angles that add up to 180.
5x+2+8x+9=180
17x+11=180-11
17x=169
x=169divided by 17
x=9.9411
x=10 when rounded into the next value
8x*10=80+989
Answer:
6^10 over 7^6.
Step-by-step explanation:
(6^5 over 7^3)^2
= 6^(5*2) / 7^(3*2)
= 6^10 over 7^6.
Team Tool Bella's average rate was 3 miles per hour.
She’s basically repeating the process over with the same numbers, so just add up 3 and 2 how many ever times to get 20 and then add the 5 and divide.
