Answer 2

To simplify the expression:

-2,4(2,5a - 1,56) + 0,5(1,86 + 5,6a)

First, distribute the coefficients outside the parentheses:

= (-2.4 * 2.5a + 2.4 * 1.56) + (0.5 * 1.86 + 0.5 * 5.6a)

Now, perform the multiplications:

= (-6a + 3.744) + (0.93 + 2.8a)

Now, collect like terms:

= -6a + 2.8a + 3.744 + 0.93

Combine the 'a' terms and the constants:

= (-6a + 2.8a) + (3.744 + 0.93)

= -3.2a + 4.674

So, the simplified expression is:

-3.2a + 4.674

Answer 3

It seems like you have an algebraic expression that involves some variables. Let's simplify it step by step.

The expression you provided is:

-2,4 (2,5 + -1,56) + 0,5 (1,86 + 5,6a)

First, perform the operations inside the parentheses:

-2,4 * (2,5 + -1,56) = -2,4 * 0,94 = -2,256

0,5 * (1,86 + 5,6a) = 0,5 * 1,86 + 0,5 * 5,6a = 0,93 + 2,8a

Now, we have simplified the expression to:

-2,256 + 0,93 + 2,8a

Now, you can add the constants together:

-2,256 + 0,93 = -1,326

So the final simplified expression is:

-1,326 + 2,8a

You can't simplify it further without knowing the value of 'a'.
