Caroline goes out to lunch. The bill, before tax and tip, was $16.15. A sales tax of 6.5% was added on. Caroline tipped 18% on the amount after the sales tax was added. The total cost of the meal plus tip and tax was more than the cost of the bill by what percent? Round to the nearest whole number.

cant open file sorry!

step-by-step explanation:

the answer is b.

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!

the answer to this is a. a^2 + b^2 = c^2
