Question

Find the value of the direct squared variation y = 12x^2 if x = 3

A. 432
B. 108
C. 1,296
D. 36

Answer 1

you would:
12(3)^2
12(9) = 108

Answer 2

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 :

`y=12x^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

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

`y\\\\=12x^2\\\\=12* 3^2\\\\=12*9\\\\=108.`

Thus, the required value is 108.

Option (B) is CORRECT.
