Question

Which expressions are equivalent to `8 (-10x+3.5y-7)`?

Answer 1

Use the distributive property to expand this expression. See details below

Explanation:

For the distributive property we will multiply `color(red)(8)` by each term within the parenthesis:

`(color(red)(8) xx -10x) + (color(red)(8) xx 3.5y) + (color(red)(8) xx -7)`

`-80x + 28y + (-56)`

`-80x + 28y - 56`
