if x: 6 as 3: 9, then x is equal to

(btw i finished history and english class : ) )

In the given expression  x:6 ::  3:9 , x  = 2

Step-by-step explanation:

Here, the given expression is:

x:6 ::  3:9

or, x : 6 = 3 :9

So, by the RATIO OF PROPORTIONALITY:

or, x = 2

Hence, in the given expression  x:6 ::  3:9 , x  = 2

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

answer: none of these answers are correct only the second half is
