Answer:
45 ways
Step-by-step explanation:
We are given;
there are 3 different math courses, 3 different science courses, and 5 different history courses.
Thus;
Number ways to take math course = 3
The number of ways to take science course = 3
The number of ways to take history course = 5
Now, if a student must take one of each course, the different ways it can be done is;
possible ways = 3 x 3 x 5 = 45 ways.
Thus, number of different ways in which a student must take one of each subject is 45 ways.
20 and 0 are your answers
Answer: The factorization of

The factors of
are 28 and 1+2t+w.
Step-by-step explanation:
The given expression : 
To factorize it, we need to find the common factor.
As 56 can be written as 2 x 28.
So, the above expression would become

Now, taking 28 as common from all the terms, we will get

Thus, the factorization of

And the factors of
are 28 and 1+2t+w.
