Question

This person did something wrong and I do not know what it is :( Please help this is for points!

Answer 1

Answer:

It is, indeed, a reduction. But, the scale factor of the dilation should be a fraction instead of a whole number, since the shape has shrunk.

Instead of $\frac{KN}{K'N'}$, it should be $\frac{K'N'}{KN}$. That would make it (4 - 2) / (8 - 4) = 2 / 4 = 1/2.

Hope this helps!
