Answer:
root 24+12 is root 36 which is equal to 6
4 root of 6 is 36 the power of 2 which is equal to 36
5 the power of 2 is 25
then when we multiple 6x36x25
it's 5400

Answer: The correct option is (A) 
Step-by-step explanation: Given that Raymond has 120 books on his bookshelf that he has not read. He plans on reading 3 books per week until there are only 24 books that he still needs to read.
We are to find the equation that can be used to determine the number of weeks it will take Raymond to have only 24 books left.
Also, we are to find the number of weeks.
The number of weeks it will take Raymond to have only 24 books left is represented by 'w'.
We have
number of books read by Raymond is 1 week = 3.
So, number of books read by Raymond is w weeks = 3w.
Since, there are total 120 books on his bookshelf, so the number of books left to read after w weeks will be

According to the given information, we get

thus, the required equation is
and number of weeks is 32.
Option (A) is correct.
The ratio A/r² would represent

which is the circumference of a circle divided by its diameter.
You can see this because the area of a circle is

r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
The sum of a number is the answer to an equation of a number plus a number you are correct.
