Question

If 4/x equal to x/9, then x is

Answer 1

Step-by-step explanation:

The value of x is 6.

Step-by-step explanation:

It is given that 4,x,9 are in G.P.

If a, b and c are in G.P., then

b^2=acb

2

=ac

x^2=4\times 9x

2

=4×9

x^2=36x

2

=36

Taking square root both the sides.

x=\sqrt{36}x=

36

x=6x=6

Therefore the value of x is 6.

hope this helps you

Answer 2

Answer:

X = 6

Step-by-step explanation:

$given \: \\ \frac{4}{x} = \frac{x}{9} \\ 4 \times 9 = x \times x \\ 36 = {x}^{2} \\ both \: the \: side \: suare \: root \\ \sqrt{36} = \sqrt{ { \times }^{2} } \\ \sqrt{6 \times 6} = \sqrt{ {x}^{2} } \\ 6 = x$
