I would pick long division because you regroup and better understand

that- y= 12/22x + 14, I think-
Step-by-step explanation:
sorry if its wrong- cuz it prolly iz but I tried-
Answer:
w= 7/4 +1/4 √89 OR w= 7/4 -1/4 √89
Step-by-step explanation:
2w^2-8w-1= (w-2)^2
Multiply (w-2)^2 by (-1)
2w^2-8w-1= -w+2^2
Add w to both sides
2w^2-7w-1= 4
Add 1 to both sides therefore that -1 cancels
2w^2-7w=5
Get the equation equal to 0 by subtracting 5 from both sides
2w^2-7w-5=0
Use the quadratic formula to solve
x= -(-7) plus or minus √(-7)-4(2)(-5)/2(2)
7 plus or minus √89/4
Answer:
900
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is given by the formula:
The polygon given has 7 sides. Substitute 7 for n. Thus:
The sum of the interior angles is 900 degrees.
