Each morning, the school librarians place 560 books on a special book shelf. Each student who visits the library that day takes exactly 3 books from the shelf. Let s be the number of students who visit the library on a particular day. Let b be the number of books left on the shelf at the end of that day. T How many books are left on the shelf the day 87 students visit the library?

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
