Step-by-step explanation:
28/81 is less than 7/9
28/81 is less than 4/9
The common denominator is 81, so you say 9 can go into 81 nine times, so you multiply 9 by the numerator, so 7/9 is now 63/81 an 4/9 is now 36/81
A ratio that is equivalent is 18:48
Answer: DQQMNGV
Step-by-step explanation: Each letter is shifted two letters to the right on a letter strip (a -> b -> c), so BOOKLET would be DQQMNGV.

Answer:
is the required factorization of f(x).
Step-by-step explanation:
To factor the expression we must first group the terms and then take out common from these groups

Taking
common from first group and the 16 from second group we get:

Now, to factor in complex from we have to break term 

As, 
Also using identity 
On solving

is the required factorization of f(x).
