Answer:

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.

LenaWriter [7]

Answer:

x = 14 inches

Step-by-step explanation:

The area of a square piece of paper is 200 square inches.

We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper. It is shown in the attached figure.

Area of a square = x², x is the side length

$x=\sqrt{A} \\\\x=\sqrt{200} \\\\x=14.142\ \text{inches}$
