Answer 2

Let's break down the given mathematical expressions step by step:

1. -1 5 - (8 1 -5 5:-11)) × 2 × 25:

First, let's simplify the expression within the parentheses: 8 1 - 5 5 / -11 = -45 / -11 ≈ 4.09 (rounded to two decimal places)

Now, the expression becomes: -1 5 - (4.09) × 2 × 25

Next, perform the multiplication: -4.09 × 2 × 25 ≈ -204.5 (rounded to one decimal place)

Finally, perform the subtraction: -15 - (-204.5) ≈ 189.5 (rounded to one decimal place)

So, the result is approximately 189.5.

2. (-2×-4x+5) + (3x-2):

This is a simple algebraic expression. Let's simplify it step by step: -2 × -4 = 8 8x + 5 + 3x - 2

Now, combine like terms: 8x + 3x = 11x 5 - 2 = 3

The simplified expression is: 11x + 3

3. • • • • 2 9 10 14:

This looks like a sequence of minus signs followed by some numbers. Assuming there are four minus signs, we can ignore them since they cancel out each other (double negatives). So, the expression becomes: 2 9 10 14

As it stands, this is not a well-defined mathematical expression. If there's any operation or pattern you want to apply to these numbers, please provide additional information or context.
