(6, 31+2pi degrees)
(6, 31+4pi degrees)
(-6, 31-pi degrees)
(6, 31-2pi degrees)
etc. etc.
Answer is 91.56 You add all the numbers up and divide by 9(There are 9 numbers in the sequence).
Undistribute x
x(m+2n)=p
divide both sides by m+2n
x=
3x = 5(x + 3) - 3 |use distributive property: a(b + c) = ab + ac
3x = 5x + 15 - 3
3x = 5x + 12 |subtract 5x from both sides
-2x = 12 |divide both sides by (-2)
x = -6
