Question

How do you simplify `4(w + 2x) + 9(-4w)`?

Answer 1

`=−color(blue)(32w)+ 8x`

Explanation:

`color(blue)(4)(w+2x)+9(−4w)`

`=color(blue)(4) * (w) +color(blue)(4) *(2x)+9(−4w)`

`=color(blue)(4w) + 8x −color(blue)(36w)`

Combining like terms:

`=color(blue)(4w) −color(blue)(36w)+ 8x`

`=−color(blue)(32w)+ 8x`
