Can someone help me?

-16t^2 + 106 = 47

t = √59/4

Step-by-step explanation:

106 - 59 = 47

-16t^2 + 106 = 47

-16t^2 + 106 - 106 = 47 - 106

-16t^2 = -59

-16t^2 / -16 = -59 / -16

t^2 = 59/ 16

√t^2 = √59/16

t= -√59/4 and √59/4

but you cant have negative time, so √59/4

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.
