3(m + 5 + 9m) part a: write two expressions that are equivalent to the given expression. part b: show that one of your expressions in part a is equivalent to the given expression using algebraic properties. explain which properties you used. part c: show that your other expression from part a is equivalent to the given expression by substituting a number for m.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
