Answer 1

Ответ:

35x-12

Объяснение:

2,5(6-4)+3(x-3)-8(1-4x)=2,5*6-2,5*4+3*x+3*(-3)-(8*1-8*4x)=15-10+3x-9-(8-32x)=15-10+3x-9-8+32x-=35x-12

Answer 2

To simplify the expression 2,5(6-4)+3(x-3)-8(1-4x), let's break it down step by step:

Step 1: Simplify the parentheses: 6 - 4 = 2 1 - 4x = -4x + 1

The expression becomes: 2,5(2) + 3(x - 3) - 8(-4x + 1)

Step 2: Multiply the coefficients outside the parentheses: 2,5(2) = 5

The expression becomes: 5 + 3(x - 3) - 8(-4x + 1)

Step 3: Distribute the remaining terms: 3(x - 3) = 3x - 9 -8(-4x + 1) = 32x - 8

The expression becomes: 5 + 3x - 9 - 32x + 8

Step 4: Combine like terms: Combine the x terms: 3x - 32x = -29x Combine the constant terms: 5 - 9 + 8 = 4

The final simplified expression is: -29x + 4.
