as a guest was sneaking away, the groundskeeper was 4 feet (48 inches) away and pushed an 84 inches ladder onto the suspect. They very top of the ladder hit the guest on the top of the head. Find the height of the guest in inches, then convert in feet. His weight is 207

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

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
