Answer:

  B.  8.9(50.9 - 18.7) = (8.9 x 50.9) - (8.9 x 18.7)

Step-by-step explanation:

If you really don't recognize the pattern of the distributive property, your calculator can tell you if the left-side expression has the same value as the right-side expression.

You are supposed to see the pattern ...

  a(b -c) = ab -ac

where a=8.9, b=50.9, c=18.7. Choice B on this list is appropriate.

  8.9(50.9 -18.7) = 8.9×50.9 -8.9×18.7
