Question

Write an equivalent expression by distributing the "minus−" sign outside the parentheses:
minus, left parenthesis, minus, 9, c, minus, 0, point, 8, d, minus, 1, right parenthesis
−(−9c−0.8d−1)

Answer 1

To distribute the minus sign outside the parentheses, we change the signs of each term inside the parentheses. Here's how it works step-by-step:

Starting with the expression:
\[
-(−9c−0.8d−1)
\]

Distributing the minus sign gives us:
\[
9c + 0.8d + 1
\]

So, the equivalent expression is:
\[
9c + 0.8d + 1
\]
