Question

3-11,5•(2-4)+4•(-2,3)

Answer 1

3-11.5•(2-4)+4•(-2,3)=3-11,5•(-2)-9,2=3+23-9,2=16,8

Answer 2

It looks like you've provided a mathematical expression that needs to be simplified. Let's break down the expression step by step:

3 - 11.5 * (2 - 4) + 4 * (-2.3)

First, let's simplify the innermost parentheses:

2 - 4 = -2

Now the expression becomes:

3 - 11.5 * (-2) + 4 * (-2.3)

Next, let's perform the multiplications:

-11.5 * (-2) = 23 4 * (-2.3) = -9.2

Now the expression becomes:

3 + 23 - 9.2

Finally, let's add the numbers:

3 + 23 - 9.2 = 16.8

So, the simplified value of the expression is 16.8.
