Answer 1

Step-by-step explanation:

It is given that (28-x) is the mean proportional of (23-x) and (19-x).

So therefore,

$( {28 - x)}^{2} = (23 - x) \times (19 - x)$

$= > ( {28)}^{2} - 2 \times 28 \times x + ( {x)}^{2} = 437 - 23x - 19x + {x}^{2}$

$= > 784 - 56x + {x}^{2} = 437 - 42x + {x}^{2}$

$= > {x}^{2} - {x}^{2} - 56x + 42x = 437 - 784$

$= > - 14x = - 347$

$= > x = \frac{347}{14}$

The value of x is 347 / 14
