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: = –22.68 Which step shows where Isaac applied the distributive property?

Answer:

Step 2

Step-by-step explanation:

Distributive Property: [tex]a(b+c)=ab+ac[/tex]

Isaac's Steps are outlined below:

[tex]\text{Step 1:} (4.2)(-5.4) = (-5.4)(4.2) \\\\\text{Step 2:} = (-5.4)(4) + (-5.4)(0.2) \\\\\text{Step 3:} = (-21.6) + (-1.08) \\\\\text{Step 4:} = -22.68[/tex]

We observe that in Step 2:

[tex](-5.4)(4.2)=(-5.4)(4+0.2)=(-5.4)(4) + (-5.4)(0.2)[/tex]

Therefore, Isaac applied the distributive property in Step 2.
