Question

А)3(2-а)+5а б)-(8+5х)-4(3х-2) в)-7(3+2n)+4(5n-3) г)-с(3+в)-в(2-с)+3с

Answer 1

Ответ:

а) 3(2-a)+5а=6-3а+5а=6+2а

б)-(8+5x)-4(3х-2)=-(8+5х)-12х+8=-8-5х-12х+8=-17х

в)-7(3+2n)+4(5n-3)=-21-14n+20n-12=6n-33

г)-c(3+b) - b(2-c) +3c=-3c-cb-2b+bc+3c=-2b

Answer 2

Иt seems like you've provided a list of mathematical expressions labeled with letters (а, б, в, г). Each expression consists of variables and arithmetic operations. It looks like you're asking for some sort of manipulation or simplification of these expressions. Could you please specify what exactly you need help with? Are you looking to simplify these expressions, solve for certain variables, or perform specific operations on them?
