Question

-1,5а •(-6b) ; -4m-15n+3m+18n ; -2•(х-3)+4•(x+1) ; b+(7-b)-(14-b) ; ВИРІШІТЬ ЦІ ПРИКЛАДИ БУДЬ-ЛАСКА ШВИДКО!!!!!!

Answer 1

Ответ:

-1,5а*(-6b) =1,5а*6b=9ab

-4m-15n+3m+18n = -4m+3m-15n+18n= -m+3n

-2*(х-3)+4*(x+1) = -2x+6+4x+4= -2x+4x+6+4=2x+10

Можно вынести общий множитель: 2*(х+5)

b+(7-b)-(14-b) =b+7-b-14+b=b-b+b+7-14=b-7
