−(−5.8d−3f−4)

Answer 1

To distribute the minus sign outside the parentheses, we need to change the signs of all the terms inside the parentheses.

The given expression is:
−(−5.8d−3f−4)

Distributing the minus sign, we get:
−1 * −5.8d − 1 * (-3f) − 1 * (-4)

Simplifying further, we have:
5.8d + 3f + 4
