Bueno Mart has a distribution warehouse in Arizona that services their stores in the southwest part of the country. At the Arizona warehouse, they have learned that to keep things running efficiently they need 4 workers for each bay and 3 supervisors for every 54 bay workers. If a new warehouse is being built in North Carolina to service the stores they are opening on the east coast, and the new warehouse is going to have 36 bays, then they will need to hire supervisors to run the new warehouse efficiently.

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!
