Answer :

you would: 
12(3)^2 
12(9) = 108

Answer:  The correct option is (B) 108.

Step-by-step explanation:  We are given to find the value of the following direct squared variation if x = 3 :

[tex]y=12x^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

For finding the value of y at x = 3, we need to substitute x = 3 in the given direct squared variation (i).

So, from equation (i), we get

[tex]y\\\\=12x^2\\\\=12\times 3^2\\\\=12\times9\\\\=108.[/tex]

Thus, the required value is 108.

Option (B) is CORRECT.
