tolong yaa teman teman
dijawab semuanya dan yg benar yaa

Answer 1

1. jika a : 40 dan b : 10 maka
 2× ( a - b ) + ( a + b )
= 2 x ( 40 - 10 ) + ( 40 + 10 )
= (2 x ( 30 )) + ( 50 )
= 60 + 50 
= 110

2.19× 325+2130 : 10 - ( 9345 - 1234 )
= (19 x 325) + (2130 : 10) - (9345 - 1234)
= (6175) + (213) - (8111)
= -1723

3. 456 × ( 1000 : 125 )
= 456 x 8
= 3648

Answer 2

1. 2× (40-10) + (40+10) = 2× 30+50 =110
2. 184`
3.456×8 =3648

Maaf kalo nomer 2 salah
