In order to solve this exercise, it is importat to remember the following information:
1. The quotient is the result of a division.
2. The sum is the result of an addition.
3. The word "twice" indicates a multiplicatio by 2.
4. The word "cube" indicates an exponent 3.
Then, keeping on mind the explained above and the data given in the exercise, you know that:
-The sum of 
and 
can be expressed as:
- Twice the cube of 
can be expressed in the following form:
Therefore, you can dermine that "the quotient of the sum of and and twice the cube of " is represented with the following expression:
O
It’s 25.5 because since 25 off of 100 equals 75, you times the 34 by .75
