Bob has 3bookshelfs that hold a total of 27 books. he adds a fourth shelf and now has 36books. if he adds 2 more shelves, how many books can he have in total

Bob will have a total of 54 books

Step-by-step explanation:

Step 1: Determine number of books per shelf

Using the expression below;

T=b×n

where;

T=total number of books

b=number of books per shelf

n=number of book shelf

In our case;

T=27 books

b=unknown

n=3

replacing;

27=b×3

3 b=27

b=27/3

b=9

Consider, when T=36, and n=4

36=b×4

b=36/4

b=9 books per shelf

It is determined that a shelf holds a standard of 9 books

Step 2: Total number of books

Using the expression;

T=b×n

where;

b=9 books per shelf

n=(4+2)=6 shelf

replacing;

T=(9×6)=54 books

Bob will have a total of 54 books

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
