<span>3x(8x-3)+6=2
24x²-9x+4=0,  a=24, b=-9, c=4
</span>x= \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a} &#10;&#10;
D= b^{2} -4ac= 9^{2} - 4*24*4 = 18-384= - 366, negative&#10;&#10;So, no real solutions.<span>

a forty-foot rope was cut into two pieces. The length of one piece is 9 times the length of the other. What is the length of the
Free_Kalibri [48]
In the question , the length of the actual rope is given as 40 foot. Also it is given that the length of one rope after cutting the original piece of rope into 2 pieces is 9 times that of the other pice.
Let us assume that the length of one piece of rope is = X
Then the length of the orther pice of rope = 9X
Now we can easily get the equation
X + 9X = 40
10X = 40
X = 40/10
X = 4
So the length of the shorter rope is 4 foot.
The length of the longer rope is 9 times that of the shorter one.
So the length of the longer rope is 36 foot.
