10. Which one of the following is a polynomial? a) 2x^(1/2) -1
b) x-1/x+1
c) x²+ 3x^(3/2) / x^(1/2)
d) (x² / 2) - (2 / x² )
​

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.

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
