Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning lights comes on when remaining fuel is 1.5 gallons or less

20 days.

Step-by-step explanation:

The question must be when the light comes on.

Well, we must first know how much fuel must be consumed so that the light comes on and is calculated as follows:

14 gallons - 1.5 gallons = 12.5 gallons

That is to say that 12.5 gallons must be consumed at least for the light to come on.

Now, to calculate the number of days you must have the daily consumption account that is 0.6 gallons and the value calculated above, in the following way you can calculate the number of days:

12.5 gallons / (0.6 gallons / day) = 20 days.

The lights will come on at 20 days, that is, at 20 days, Diego's dad should fill the car with fuel.

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!
