Question

Write an equivalent expression by distributing the "minus−" sign outside the parentheses:
minus, left parenthesis, 2, p, plus, 4, point, 1, q, plus, 7, right parenthesis
−(2p+4.1q+7)

Answer 1

To distribute the minus sign outside the parentheses in the expression \(- (2p + 4.1q + 7)\), you multiply each term inside the parentheses by \(-1\):

\[
- (2p) - (4.1q) - (7)
\]

This simplifies to:

\[
-2p - 4.1q - 7
\]

So, the equivalent expression is:

\[
-2p - 4.1q - 7
\]
