Question

If 14 is the mean proportional between x and 28; find the value of x​

Answer 1

Answer:

Step-by-step explanation:

when we see mean proportional, the form is

14 : x : 28

therefore,

14/x = x/28

$x^{2}$ = 28 x 14

$x^{2}$ = 392

x = $\sqrt{392}$

Answer 2

x:14::14:28

$\frac{x}{14} = \frac{14}{28} \\ x = \frac{14 \times 14}{28} \\ x = 7$
