|1| identify the property shown. 3 x (k + 4) = 3 x k + 12 a. transitive b. associative c. commutative d. distributive |2| which is an example of the distributive property? a. 9 x (t + 5) = 9t + 45 b. 9 x (t + 5) = (t + 5) x 9 c. 9 x (t + 5) = ( 9 x t) + 5 d. 9 x (t + 5) = 9t + 5 |3| identify the property shown. 6 x w + w x 6 a. transitive b. associative c. commutative d. distributive |4| which could be next step in simplifying this expression if you wanted to use mental math? 24 + (6 + 29) a. 24 x 6 + 24 x 29 (use the distributive property) b. 24 x 6 + 29 (use the associative property) c. (24 + 6) + 29 (use the associative property) d. 24 + 6 x 29 (use the commutative property) |5| which property justifies this statement? r(s + t) + rs + rt a. associative b. distributive c. symmetric d. transitive this is all from k12| if you get something wrong i will tell you so when others view this they get the correct answer! good luck!

Answer i need it quick patti is using mental math to evaluate the expression (70 + 12.8 + 30) + 6.1. she recognizes that the expression will be easier to simplify if she can combine 70 and 30 before she works with the other numbers. how do the properties of operations allow patti to take that approach? she can use the associative property to rewrite the expression as (70 + 30) + 12.6 + 6.1. she can use the associative property to rewrite the expression as (70 + 30 + 12.8) + 6.1. she can use the commutative property to rewrite the expression as (70 + 30) + 12.8 + 6.1. she can use the commutative property to rewrite the expression as (70 + 30 + 12.8) + 6.1.
