4 0

Answer:

The dialation is of 2

Step-by-step explanation:

QR = 3 units

QS = 2 units

RS = 2 units

Q'R' = 6 units

Q'S' = 4 units

R'S' = 4 units

So as you can see, this triangle has doubled it's size, since it has been multiplied by 2.

Hope this helped!

Step-by-step explanation:

  3\dfrac{1}{5}+2\dfrac{1}{5}\div\dfrac{5}{11}-3\dfrac{2}{5}\times\left(-1\dfrac{1}{4}\right)\qquad\text{given}\\\\=\dfrac{16}{5}+\left(\dfrac{11}{5}\cdot\dfrac{11}{5}\right)-\left(\dfrac{17}{5}\cdot\dfrac{5}{4}\right)\\\\=\dfrac{16}{5}+\dfrac{121}{25}-\dfrac{17}{4}=\dfrac{320+484-425}{100}=\dfrac{379}{100}\\\\=\boxed{3\dfrac{79}{100}}
