Question

-(-4,9 -5,8c ) -(3,1c-5,6)

Answer 1

-(-4,9-5,8с)-(3,1с-5,6)=4,9+5,8с-3,1+5,6=7,4+5,8с

Answer 2

To simplify this expression, we need to distribute the negative sign to each term inside the first set of parentheses.

-(-4.9 - 5.8c) becomes 4.9 + 5.8c.

Next, we can distribute the negative sign to each term inside the second set of parentheses.

(3.1c - 5.6) becomes -3.1c + 5.6.

Now, we can substitute these expressions back into the original expression and simplify:

4.9 + 5.8c - (-3.1c + 5.6)

= 4.9 + 5.8c + 3.1c - 5.6 (using the rule a - (-b) = a + b)

= 9.9 + 8.9c

Therefore, the simplified expression is 9.9 + 8.9c.
