Answer: 10 inches.
Step-by-step explanation:
Since the pecan pie is a circle, you can use this formula:
Where "r" is the radius and 
is the central angle of the arc in radians.
If the pecan pie has been cut into 8 equal pieces then the central angle is:
Now you know the arc length and the central angle, then, you can solve for "r" from :
Substituting values, you get that the radius of the pecan pie rounded to the nearest whole number is:
Answer: -7, 12
Step-by-step explanation:
a+b = 5
a*b = -84
a = 5-b
(5-b)*b = -84
-b^2 + 5b + 84 = 0
(-b - 7)(b + 12) = 0
The roots are -7 and 12.
