Isaac applied the steps below to find the product of (4.2)(–5.4).Step 1: (4.2)(–5.4) = (–5.4)(4.2) Step 2: = (–5.4)(4) + (–5.4)(0.2)Step 3: = (–21.6) + (–1.08)Step 4: = –22.68Which step shows where Isaac applied the distributive property?

The distributive property breaks one factor into a sum and multiplies each part separately: a(b + c) = ab + ac. In Step 2, Isaac rewrites 4.2 as 4 + 0.2 and multiplies −5.4 by both parts. So the distributive property is applied in Step 2, choice B.
