Find the product. (8x 2 + 12xy + 16y 2)(2x - 4y)

answer: -8.2562234e+13

answer: it's a

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
