A movie theater charges $15 for standard viewing, $20 for 3D viewing, and $35 for Dinner and a Movie viewing. There are four times as many 3D viewing seats as Dinner and a Movie seats. If the theater brings in $53,000 when tickets to all 3000 seats are sold, determine the quantity of each type of seat in the movie theater.

m∠a is 90°

m∠b is 40°

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!
