write an equivalent expression by distributing the \-\ sign outside the parentheses: -(7n + 2.1)

write an equivalent expression by distributing the \-\ sign outside the parentheses: -(7n + 2.1)

Answer

Explanation:

Step1: Distribute the negative sign

We know that $-(a + b)=-a - b$. Here $a = 7n$ and $b=2.1$. So, $-(7n + 2.1)=-1\times(7n+2.1)=(-1)\times7n+(-1)\times2.1$.

Step2: Simplify each term

$(-1)\times7n=-7n$ and $(-1)\times2.1=-2.1$. So the equivalent expression is $-7n - 2.1$.

Answer:

$-7n - 2.1$
