Question

What is the scale factor applied to Figure A toproduce Figure B.A. 9B. 6C. 12D. 3

Answer 1

ANSWER

D. 3

EXPLANATION

We want to find the scale factor applied from figure A to figure B.

To do that, we have to divide any of the side lengths of figure B by a corresponding side length of figure A.

Let us divide the side length of the left sides of both figures.

Therefore, the scale factor is:

$\begin{gathered} SF=\frac{18}{6} \\ SF=3 \end{gathered}$

That is the scale factor.
