Answer:
A circle with circumference 18 had an arc with 120 central angle.
=> Radius of that circle: R = 18/(2 x pi) = 2.86
=> Length of that arc: L = R x 120 x pi/180 = 2.86 x (2/3) x pi = 5.99
Hope this helps!

Simplify both brackets, this equals 22 + 10x - 17 + 5x
Simplify further and you get 15x + 5
Using synthetic division, with divisor -4 stemming from factor (x+4), we find the coefficients of the quotient:
____________________
-4 / -3 -4 2
12 -2
------------------------------------
-3 8 0
The quotient is then -3x + 8, using the coefficients derived using synth. div.
2^10=1024
(a^m)^n=a^(m*n)
------------------
(2^(10))^(-1/5)
=2^(-10/5)
=2^(-2)
=1/4 (As the inverse of 2^2 is 1/4)
Maybe you should work on starting you're sentences.
