Answer 2

Observe the change of the values x and y.

\(\LARGE\bf{x: 2 \rightarrow 6}\)

\(\LARGE\bf{y:6 \rightarrow 18}\)

We can divide to find by how much they are dilated.

\(\LARGE\bf{x: \frac{6}{2} \rightarrow 3}\)

\(\LARGE\bf{y: \frac{18}{6} \rightarrow 3}\)

We see that it `expansed` by a scale factor of `3`.

Answer 4

You can count the units of the sides of the two squares to see how much it `expansed`.

The `square ABCD` has length and width of 1, while as `square A'B'C'D'` has a length of 5. So the scale factor is `5`.
