Question

Does 4(2x-5) equal 8x-5 or 8x-20? explain

Answer 1

`4(2x-5)` is equal to
`8x-20`.

Because, when multiplying an integer with a bracket, you multiply the integer with all the stuff in it.

Like this,


`a(bx+c)=\quad a\cdot bx+b\cdot c`

So if we expand the expression
`4(2x-5)`


`4(2x-5)=\quad 4\cdot 2x+(4\cdot -5)\quad \Longrightarrow \quad 8x+(-20)\quad \Longrightarrow \quad 8x-20`

Answer 2

4(2x-5)
8x-20

it is equal to 8x-20 because you simplify it and it turns into that.
