for #25 it would be C because distributive property is multiplying a single term and two other terms inside a parenthesis. for example 5(2+8).
For the second question your answer is 5 because in order for all the bouquets to have the same number of flowers there has to be 8 sets with 9 red flowers in it which equal 72. so if you have 8 sets then you would put 5 white flowers in each to equal 40.
