Answer 1

Answer:

C

Step-by-step explanation:

The distributive property says that

$a\cdot (b+c)=a\cdot b+a\cdot c$

Consider option C. In this option,

$(0.7\cdot 0.7)+(0.7\cdot 0.9)+(0.7\cdot 0.2)=0.7\cdot (0.7+0.9+0.2)$

The left part consists of three products

$(0.7\cdot 0.7)\\ (0.7\cdot 0.9)\\ (0.7\cdot 0.2)$

Each of these products has the factor $0.7.$ Usig the distributive property, we can write this factor before the brackets and all remaining factors write as the sum in the brackets:

$0.7\cdot (0.7+0.9+0.2)$

This is exactly the right part of equality from option C.
