Instead of plugging in and right away, notice that

and now evaluating this expression at the two given values is easier, if only a little:

ii6tyhj7 juj3yyj333ju jmyhthhtk7h jg hajj jiijh

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
