Question

2(х+4)-4(5-х)-(4+2)х-3

Answer 1

Ответ:

-15

Объяснение:

2(х+4)-4(5-х)-(4+2)х-3.

1. раскроем скобки: 2х+8-20+4х-6х-3

2. ищем подобные члены: 2х+4х-6х-3-20+8

получается -15.

Answer 2

$2(x+4)-4(5-x)-(4+2)x-3=\\=2x+8-20+4x-6x=\\=2x+4x-6x+8-20=\\=0x-16=-16.$

Answer 3

To simplify the given expression, let's perform the calculations step by step:

Given expression: 2(x+4) - 4(5-x) - (4+2)x - 3

Step 1: Distribute the coefficients outside the parentheses: 2x + 8 - 20 + 4x - 4x - 2x - 3

Step 2: Combine like terms: (2x + 4x - 4x - 2x) + (8 - 20) - 3 0 + (-12) - 3

Step 3: Simplify the expression: -12 - 3 = -15

So, the simplified value of the expression is -15.
