1.
a salesperson is selling cooking sets for $120 each. the salesperson
receives 22.5% of the sales price as commission. the salesperson sells a
total of 4 units on monday but an unknown number of units on tuesday.
the salesperson made a combined total of $351 commission for those two
days. write an equation that could be used to find the number of cooking
sets x sold on tuesday. then solve the equation.

answer: its because of life

step-by-step explanation: i dont know

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!
