Answer 1

Ответ:

3*5.1x-3*2.5-0.9*17x-0.9*5

15.3x-6-15.3x-4.5

15.3x-15.3x-6-4.5=-10.5

Answer 2

It seems like you're trying to express an algebraic expression, but the formatting is a bit unclear. I'll assume you have two terms that you want to simplify:

1. 3(5x - 2, 5)
2. -0.9(17x + 5)

Let's simplify each term:

1. 3(5x - 2.5)

To simplify, distribute the 3 into the terms inside the parentheses:

= 3 * 5x - 3 * 2.5 = 15x - 7.5

2. -0.9(17x + 5)

Again, distribute the -0.9 into the terms inside the parentheses:

= -0.9 * 17x - 0.9 * 5 = -15.3x - 4.5

So, your simplified expression is:

15x - 7.5 - 15.3x - 4.5

Now you can combine like terms:

(15x - 15.3x) + (-7.5 - 4.5)

-0.3x - 12

So, the simplified expression is -0.3x - 12.
