A. 3,8,and 19
B. 13,23,and 41
C. 11, 17, and 26
D. 15, 16, and 17​

Answer 1

Step-by-step explanation:

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

=} 3+(8+19) = (3+8)+19

=} 3+27 = 11+19

=} 30 = 30

HENCE, a+(b+c) = (a+b)+c

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

=} 13+(23+41) = (13+23)+41

=} 13+64 = 36+41

=} 77 = 77

HENCE, a+(b+c) = (a+b)+c
