Question

0,2-2(х 1)-0,4(х-10)

Answer 1

$0,2-2(x+1)-0,4(x-10)=$
$=0.2-2x-2-0.4x+4=$
$=2.2-2.4x$

Answer 2

To simplify the expression 0,2-2(х+1)-0,4(х-10), we need to distribute the coefficients of the terms inside the parentheses:

0,2 - 2x - 2 - 0,4x + 4

Next, we can combine like terms by adding or subtracting coefficients of the same variable (x):

-2,4x + 2,2

Therefore, the simplified expression is -2,4x + 2,2.
