Triangle TUV has been dilated to form triangle TꞌUꞌVꞌ.
What is the scale factor?

Answer:
4.4, 4.4 : 1, 22 : 5
Step-by-step explanation:
There are many ways to solve this, but I'll do it by finding the ratio between V'T' and VT.
That's easy, we're given the lengths of these two. The ratio would be 8.8/2. 8.8/2 = 4.4, or (8.8*5)/(2*5) = 22/5
