suppose, you are rolling two regular six-sided dice and two four-sided dice together. let’s say, the sum of the numbers appearing on the two regular six-sided dice is ‘a’ and the sum of the numbers appearing on the two four-sided dice is ‘b’. what is the probability that the product of a and b is 12?

investment b is an ordinary annuity with $3,909.64 in the account after one year.

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!
