Need help with this i don’t get it

Step-by-step explanation:

To create a scale copy, all length of the segments that makes up the original figure is multiplied by a certain number to get the new length of all segments of the scaled copy. That number is the scale factor.

The ratio of the corresponding side lengths of the scaled copy and the original copy = the scale factor.

In polygon PQRS (scaled), length of side PS = 3 units.

In polygon ABCD (original figure), length of side AD = 2 units.

PS corresponds with AD.

Therefore, = scale factor.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

it is not that hard all u have to do is plot the graph
