To factor a quadratic of the form ax^2+bx+c you need to find two values, j and k, which satisfy two conditions...
jk=ac=12 and j+k=b=8, so j and k must be 2 and 6
Then the factors are just (a+j)(a+k), in this case:
(a+2)(a+6)
So the missing term was 6
Answer:
2
Step-by-step explanation:
The side has to be between the angles.
So, Angle1 - Side - Angle2
So, we can only swap the angles. So no other permutation is possible with the given conditions.

Answer:
Formula for the Arc length is given by:

As per the statement:
radius of circle(r) = 6 units
Angle (
) =
radian
Use conversion:

= 
then;
substitute these given values we have;
Use value of 

or

Simplify:

Therefore, the arc length of the arc substended in a circle with radius 6 units an angle of 7 pi/8 is 16.485 units
