Answer 1

Answer:

brainlinest and thank me plzzz

Step-by-step explanation:

9, 12, x are in continued proportion. Then the value of x​ is 16

Given 9,12,x are in continued proportion.

We know if a,b,c are in continued proportion

In this case a=9,b=12,c=x

so 9x=  12 x 12

or 9x=   144

or x=  144/9

or x=16

so the value of x is 16

Answer 2

Answer:

16

Step-by-step explanation:

continued proportion is that the middle no is repeated twice in proportion so,

according to question proportion=

9:12::12:x

= as we know that product of extreme= product of mean

= 9 × x = 12×12

= 9x = 144

= x = 144/9= 16

so value of x is 16
