Habisin poin O-o lage_-
penyelesaian :
batas nya adalah 5 dan variabel X diketahui adalah 1 sampai 5 jadi :
= ( 1x + 3 ) + ( 1x + 3 ) + ( 1x + 3 ) + ( 1x + 3 ) + ( 1x + 3 )
= ( 1 (1) + 3 ) + ( 1 (2) + 3 ) + ( 1 (3) + 3 ) + ( 1 (4) + 3 ) + ( 1 (5) + 3 )
= ( 1 + 3 ) + ( 2 + 3 ) + ( 3 + 3 ) + ( 4 + 3 ) + ( 5 + 3 )
= 4 + 5 + 6 + 7 + 8
= 9 + 13 + 8
= 22 + 8
= 30
= (1(1) + 3) + (1(2) + 3) + (1(3) + 3) + (1(4) + 3) + (1(5) + 3)
= (1 + 3) + (2 + 3) + (3 + 3) + (4 + 3) + (5 + 3)
= 4 + 5 + 6 + 7 + 8
= 9 + 6 + 7 + 8
= 15 + 7 + 8
= 22 + 8
= 30
