Diep is saving money so he can buy a used car in 12 months. the total cost of the car he wants is $1,450. diep determines that he needs to save $120 each month to be able to afford the car, as shown below. mc024-1.jpg what error did diep make? there is a subtraction error. diep will need to save less than $120 each month. there is a subtraction error. diep will need to save exactly $121 each month. there is a multiplication error. diep needs to save exactly $120.83 each month. there is a multiplication error. diep needs to save an average of mc024-2.jpg each month. some months he needs to save $120.83 and other months he needs to save $120.84.

The answer is D. There is a multiplication error. Diep needs to save an average of $120.833... each month. Some months he needs to save $120.83 and other months he needs to save $120.84

step-by-step explanation:

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!
