write an equivalent expression by distributing the \-\ sign outside the parentheses: -(-9c - 0.8d - 1)

Answer

Explanation:

Step1: Recall distributive property

When we have $-(a + b + c)=-a - b - c$. Here $a=-9c$, $b = - 0.8d$, $c=-1$.

Step2: Distribute the negative sign

$-(-9c-0.8d - 1)=-1\times(-9c)-1\times(-0.8d)-1\times(-1)$.

Step3: Calculate each term

$-1\times(-9c)=9c$, $-1\times(-0.8d)=0.8d$, $-1\times(-1) = 1$.

Answer:

$9c + 0.8d+1$
