What is your guess?
OpenStudy (freckles):
you are given 2a+(b+7c) They just want you to use properties like associative property.
OpenStudy (shaleiah):
I'd say 2a+2b+7c
OpenStudy (freckles):
(m+n)+z=m+(n+z) by associative property none of the numbers change just the grouping symbols changed location
OpenStudy (freckles):
example 5+(3+2) =(5+3)+2
