Answer:

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.

Answer:

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.
