If 3x-y=12, what is the value of 8x2y?

A) 212

B) 44

C) 82

D) The value cannot be determined from the information given.

D.

Step-by-step explanation:

3x - y = 12 or:-

y = 3x - 12

There are infinitely many values for x and y which fit this relation, so the value of 8x2y cannot be determined from the given information.

D

Step-by-step explanation:

3x-y=12

rearranging y=3x-12 or x=y/3+4

8x*2y

=8x * (3x-12) or 8 (y/3+4) * 2y

=24x^2-96x or 16y^2/3+64y

either one value cannot be determined unless x or y is known

so ans is D) The value cannot be determined from the information given.
