Question

2(2х+4)-3(5х-4)............

Answer 1

2(2х+4)-3(5х-4)=4х+8-15х+12=-11х+20;

Answer 2

To simplify the expression 2(2x + 4) - 3(5x - 4), we can apply the distributive property and combine like terms. Let's break it down step by step:

First, distribute the 2 to the terms inside the parentheses: 2 * 2x + 2 * 4 - 3(5x - 4)

This gives us: 4x + 8 - 3(5x - 4)

Next, distribute the -3 to the terms inside its parentheses: 4x + 8 - 3 * 5x + 3 * 4

This simplifies to: 4x + 8 - 15x + 12

Now, combine the like terms, specifically the terms with x and the constant terms: (4x - 15x) + (8 + 12)

Combining the x terms gives us: -11x

Combining the constant terms gives us: 20

Therefore, the simplified expression is: -11x + 20
