Question

$$-8(n-9)-10(8n+4)$$

Evaluate

$32-88n$

Solution Steps

Use the distributive property to multiply $-8$ by $n-9$.

$$-8n+72-10\left(8n+4\right)$$

Use the distributive property to multiply $-10$ by $8n+4$.

$$-8n+72-80n-40$$

Combine $-8n$ and $-80n$ to get $-88n$.

$$-88n+72-40$$

Subtract $40$ from $72$ to get $32$.

$$-88n+32$$

Expand

$32-88n$

Solution Steps

Use the distributive property to multiply $-8$ by $n-9$.
