Answer:
1080 degrees
Step-by-step explanation:
A regular octagon has 135 degrees per interior angle. To find the sum, add 135 for each angle. There are 8 interior angles.
8*135 = 1,080
Answer: D. -40x^3+25x^2+45x
Answer:
(x + 4)² + (y - 12)² = 3
Step-by-step explanation:
form of circle
(x - h)² + (y - k²) = r²
(h, k) is the center = (-4, 12
r is the radius =√3
------------------------
plug in the givens
(x + 4)² + (y - 12)² = 3
First move the constant to the other side causing it to change sides
4x<-6-6
Then calculate the difference (-6-6)
4x<-12
Now divide both sides by 4
X<-3
Then you are left with your answer:
x<-3
Hope this helps! :3
