The ways in which he can make selection = 
Step-by-step explanation:
Student is having a list of 
books.
Assuming that the student can't read the same book twice.
The student has 
choices to make for an outside reading requirement,for his 1st choice, he had books to choose from; for his 2nd, he has 
books left to choose from therefore the total permutations of his choices are 
So the total ways in which the student can make his selection = 
Answer:
-3
Step-by-step explanation:
We know that both the larger triangle is dialated by some factor.
To start divide the two given sides:
36/24=1.5
This means that the larger triangle is dialated by a factor of 1.5, meaning that all sides of the smaller triangle must be multipled by 1.5 to get the larger triangle.
By knowing that we can multiply 3x-7 by 1.5 and set it equal to 6x-6.
1.5(3x-7)=6x-6
4.5x-10.5=6x-6
-6x+4.5x=10.5-6
-1.5x=4.5
x=(4.5)/(-1.5)
x= -3

Answer:
V = 6.26 (2.5)
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
V = (2.5)^3
V = 6.26 (2.5)
Answer:No
Step-by-step explanation:
first values is 3x+x = 4x
second value is x(2+1) = x(3) = 3x
since 3x!=4x . answer is no.
