We need to apply distributive property on each of the given expressions to write their equivalent expressions.
(1) [tex]-3(2x-4)[/tex]
Upon using distributive property, we get:
[tex](-3)(2x)+(-3)(-4)\\ -6x+12[/tex]
(2) [tex]0.1(-90+50a)[/tex]
Upon using distributive property, we get:
[tex]-9+5a[/tex]
(3) [tex]-7(+50a)[/tex]
This part is incomplete.
(4) [tex]\frac{4}{5}(10y+-x+-15)[/tex]
Upon using distributive property, we get:
[tex]\frac{4}{5}(10y)+\frac{4}{5}(-x)+\frac{4}{5}(-15)\\ 8y-\frac{4x}{5}-12[/tex]
