Paul has a mix of quarters and dimes in his piggybank. He has twice as many dimes than he has quarters. He counts all his coins and notices that he has 9.00$ in total. How many quarters does Paul have?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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.
