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

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

$(8 \times - 10 x) + (8 \times 3.5 y) + (8 \times - 7)$ $(color(red)(8) xx -10x) + (color(red)(8) xx 3.5y) + (color(red)(8) xx -7)$

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

$- 80 x + 28 y - 56$ $-80x + 28y - 56$

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