b)3.2
c)11.2
d)-3.2
11) What is the opposite of
12)
13)
14)

 (10) 3.2   (11) option 2   (12) option 4  

               (13) Distributive  (14) Associative

Step-by-step explanation:

10) "Absolute value" makes the number positive.

       - |-4| + |-7.2|

   =  -  4  +  7.2

   =       3.2

11) "Opposite" changes the sign.

    the opposite of       is    

12) Reciprocal means "flip" the fraction

     the reciprocal of         is    

13) a(b + c) = ab + ac    is the Distributive Property

 =  

 =  

14) a · (b · c) = (a · b) · c     is the Associative Property

  =
