<h2>Answer:</h2>

The error interval for x is:

                  [3.65,3.74]

<h2>Step-by-step explanation:</h2>

The number after rounding off is obtained as:

                          3.7

We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:

   3.65     3.66    3.67    3.68    3.69    3.70    3.71   3.72    3.73    3.74

( Because if we have to round off a number present in decimals to n place then if  there is a  number greater than or equal to 5 at n+1 place then it will result to the one higher digit  at nth place on rounding off and won't change the digit if it less than 5 )

         Hence, the error interval is:

             [3.65,3.74]

Step-by-step explanation:

if 2 chords of a circle intersect , then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

KN × JN = LN × MN

(x - 4)(x + 23) = (x + 14)(x - 1) ← expand factors on both sides using FOIL

x² + 19x - 92 = x² + 13x - 14 ( subtract x² from both sides )

19x - 92 = 13x - 14 ( subtract 13x from both sides )

6x - 92 = - 14 ( add 92 to both sides )

6x = 78 ( divide both sides by 6 )

x = 13
