Solve the equation

X=
Or x=

x = 2 orx = 7

Step-by-step explanation:

   (4x - 8)(x - 7) = 0

⇔

   4x - 8 = 0 or x - 7 = 0

⇔

   x = 8/4 or x=7

⇔

   x = 2  or  x = 7

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
