Which polygon in the diagram cannot be mapped onto the others by similarity transformations?

  B.) PQRST

Step-by-step explanation:

There are no options but if its the same question I just had on a test then this is the answer..

Hope this helps..

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
