The area of aron's favorite poster is 6 square feet. the length of the poster is 3 feet. find the width of the poster

The width is 2 ft

Step-by-step explanation:

We know the area of a rectangle is

A = l*w

The area is 6 and the length is 3

6 = 3*w

Divide each side by 3

6/3 = 3w/3

2 =w

The width is 2 ft

if x decreases by 4 then y increases by 10

step-by-step explanation:

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
