△pqr maps to △vwx with the transformation (x, y) (x + 3, y − 1) (3x, 3y). if wx = 12, what does qr equal? (i made the error show for additional into solving this)

The measure of QR is 4.

Step-by-step explanation:

It is given that △PQR maps to △VWX.

The transformation is defined as

It means first transformation is translation and second transformation is dilation.

Translation is a rigid transformation. It means the corresponding sides of image and preimage are same.

Dilation is defined as

From the given rule it is clear that the value of k is 3 it means the dilation factor is 3. It means the corresponding sides of image are 3 times of the preimage.

Therefore the measure of QR is 4.
