A scale drawing of a car uses a scale of 1 inch = 3 feet. The length of the car in the scale drawing is 6 inches. Which proportion can be used to find the length of the actual car?

18 feet

Step-by-step explanation:

Since 1 inch would be 3 feet this would mean that you would multiply each inch by 3 to find out the actual length

Therefore 3 x 6 = 18

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!
