Question

Saac 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?
Step 1
Step 2
Step 3
Step 4

Answer 1

Step 2: = (–5.4)(4) + (–5.4)(0.2) this step is applied the distributive property

hope it helps

Answer 2

Answer: Step 2

Explanation:

The distributive property is given by :-

(a+b)c=ac+bc, where a,b and c are any number.

The given expression :
`(4.2)(-5.4)`

The above expression can be written as :

`(4+0.2)(-5.4)`

When we apply distributive property to the given expression, we get

`(4)(-5.4)+(0.2)(-5.4)\\\\=(-5.4)(4)+(-5.4)(0.2)`

Hence, Step 2 shows the distributive property applied by Isaac.
