Question

How do you simplify `7(-2x+10)`?

Answer 1

`7(-2x+10)=color(blue)(-14x+70)`

Explanation:

The distributive property (of multiplication over addition) tells us that in general:
`color(white)("XXX")a(b+c)=ab+ac`

Therefore
`color(white)("XXX")7(color(green)(-2x)+color(orange)(10))=color(green)(7xx(-2x))+color(orange)(7xx10)`

`color(white)("XXXXXXXXXXX")=color(green)(-14x)+color(orange)(70)`
