Answer 2

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

1. Distribute the 2,5 to the terms inside the parentheses: 2,5 * 4a = 10a 2,5 * (-8b) = -20b

   The expression now becomes: 10a - 20b - (3a - 4b)1,4

2. Distribute the -1,4 to the terms inside the parentheses: -1,4 * 3a = -4,2a -1,4 * (-4b) = 5,6b

   The expression now becomes: 10a - 20b - 4,2a + 5,6b

3. Combine like terms: (10a - 4,2a) - (20b + 5,6b) = 5,8a - 14,4b

So, the simplified form of the expression 2,5(4a-8b)-(3a-4b)1,4 is 5,8a - 14,4b.
