Nadia is making a copy of an image on the copy machine. she needs to enlarge it, and decides to enlarge it by a scale factor of three. if one side of the original is 1 1/2 in., how big is that same side after she makes the copy?

Step-by-step explanation:

We know that one side of the original is

Also, the copy machine enlarges the original by a scale factor of three. This means that the enlarged result is three times bigger that the original. Remember that a scale factor multiplies the original measure.

So, the bigger copy would be

Therefore, the image changed from to .

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
