Sorry i can’t quite see the image can you do another one
8/12 in simplest form is 2/3.
The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it
Answer:
The mid-point is (9,-9/2)
Step-by-step explanation:
You would use the mid-point formula for this

if you plug that in it is (
)
resulting in (11/2,-2/2) = (11/2,-1)
The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
