Please dear please tell no spam please needed urgently. If you have an older to help you ask her and tell me please no spam​

Answer 1

Answer:

Ascossative=(a+b) +c=a+(b+c)

a= 31 b= 16 c=30

(31+16)+30=31+(16+30)

47+30=31+46

77=77

hence, proved

I hope my answer helps you☺☺

Answer 2

Answer:

Hello !, hope this helps u,

Associative property :- 31 +16 +30

                          31+ (16+ 30) = (31 +16) +30

                             31 + 46 = 47 +30

                                  77 = 77.

Commutative property :-

              31 +16 +30 = 30 + 16 +31

                     47 +30 = 46 + 31

                            77 = 77

Associative and Commutative properties always holds true for addition.
