Question

if 25:x =x:9 the find the value of x​

Answer 1

Answer:

X=15

Step-by-step explanation:

25/x=x/9

=25×9=x^2

=5×3=x. .... Taking square roots

15=x

Answer 2

$\underline{ \underline{ \sf \maltese\:{Given:-}}}$

• 25 : x = x : 9

$\underline{ \underline{ \sf \maltese \:{To \: find:-}}}$

• The value of x

$\underline{ \underline{ \sf \maltese \:{Solution:-}}}$

We know that:-

• $\boxed{\rm{Product ~of~means = Product ~of ~extremes}}$

⇒ x² = 25 × 9

⇒ x² = 225

⇒ x = $\sqrt{225}$

⇒ x = 15

•°• the value of x = 15
