Select from the drop-down menu to correctly identify the property shown. (−3.4+(−9.2))+(−5.6)=−(3.4+9.2)+(−5 .6)

For this case we have the following expression:
 (-3.4 + (- 9.2)) + (- 5.6)
 Applying the distributive property we can rewrite the expression.
 The distributive property consists in multiplying the values that are inside a parenthesis, by a value that is outside the parentheses.
 Therefore, the value outside the parenthesis is -1.
 We have then:
 - (3.4 + 9.2) + (- 5.6)
 
 Distributive property.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
