Can anyone explain how to solve this?

2n*p/1n

Step-by-step explanation:

you pretty much just start reducing, so you would take the 3n and subtract it by 3n and take 4n and subtract by the 3n because what you do to the top you do to the bottom

sorry if it wasn't explained right, this was the way i was taught

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
