Question

3(х-4)-6(х+5)-3(3х-7)

Answer 1

3(х-4)-6(х+5)-3(3х-7)=3х-12-6х-30-9х+21=-12х-21

Answer 2

Ответ:

= -12x -42

Пошаговое объяснение:

3(х-4)-6(х+5)-3(3х-7)=

3*x + 3*(-4) -6*x -6*5 -3*3x -3*(-7)=3x-12-6x-30-9x= -12x -42

Answer 3

To simplify the expression, let's distribute the constants and coefficients:

3(x - 4) - 6(x + 5) - 3(3x - 7)

First, distribute the constants: 3x - 12 - 6x - 30 - 9x + 21

Now, combine like terms: (3x - 6x - 9x) + (-12 - 30 + 21)

Simplify the x terms: -12x + (-21)

Combine the constants: -12x - 21

So, the simplified expression is -12x - 21.
