o Watch help videoVW is dilated by a scale factor of 4 to form V'W'. V'W' measures 80.What is the measure of VW?Answer:Submit Answerattempt 1 out of 2

Answer 1

Let L be the original lenght of segment VW. Taking this lenght and dilating it by a scale of 4 will give us the expression:

`4L`

If we know that after the dilation we'll have a lenght of 80, we'll have the equation:

`4L=80`

Solving for L,

`\begin{gathered} 4L=80\rightarrow L=(80)/(4) \\ \\ \Rightarrow L=20 \end{gathered}`

Therefore, we can conclude that the original length of segment VW was 20
