Solve |2x - 6| > 10 a. {x|x < -8 or x > 2} b. {x|x < -2 or x > 8} c. {x|-2 < x < 8}

2x - 6 > 10 or 2x - 6 < -10
2x > 10 + 6 or 2x < -10 + 6
2x > 16 or 2x < -4
x > 16/2 or x < -4/2
x > 8 or x < -2

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
