480700. The different combinations of students that could go on the trip with a total of 25 student, but only 18 may go, is 480700.
The key to solve this problem is using the combination formula 
. This mean the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.
The total of students is n and the only that 18 students may go is r:
10 because there is 4 zero's behind the one. Hopes this helps!! :)
Answer:
Step-by-step explanation:
lateral surface area=(sum of sides)×height
Total surface area =2×base area +lateral area
Step-by-step explanation:
by comparing both f (x) and g (x)
we get
3x-1=2x-1/x
by this way we can get the value of X and put the value of X in f (x) and g (x)
