Question

-4 ∙ (7 - 2х) + 6 ∙ (3х - 5)

Answer 1

Ответ:

-4×(7-2x)+6×(3x-5)= -2(2(7-2x)-3(3x-5))=-2(14-4x-9x+15=-2(29-13x)

Answer 2

Ответ:

-28+8х+18х-30=26х-58

Answer 3

Let's simplify the expression step by step:

$-4 \cdot (7 - 2x) + 6 \cdot (3x - 5)$

First, distribute the multiplication:

$-28 + 8x + 18x - 30$

Combine like terms:

$26x - 58$

So, $-4 \cdot (7 - 2x) + 6 \cdot (3x - 5) = 26x - 58$.
