Answer:
i) around 41.7 kg
ii) 72 books
Step-by-step explanation:
i) if 108 books are 30 kg then how much is the mass for 150? You cross multiply so 150 multiply by 30 and 108 multiply by x (the unknown mass). you will get 4500=108x and then 4500/108 is the unknown mass.
ii) use the same way as above.
The correct answer is: No, the remainder is -114
Further explanation:
In order to check whether the given term is a factor of given polynomial or not we will put
x+2=0
x=-2
Given

As the remainder is -114, the term x+2 is not a factor of given polynomial
The correct answer is: No, the remainder is -114
