(2 points) the quantity of 2x plus 15, all over the quantity of 4x plus 11 the quantity of 4x squared plus 40x plus 81, all over the quantity of 4x plus 11 the quantity of 2x plus 15, all over the quantity of 3x squared plus 19x plus 28 the quantity of 4x squared plus 40x plus 81, all over the quantity of 3x squared plus 19x plus 28

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
