PLEASE, I NEED ANSWER NOW!
Molly had $30 in a savings account. The simple interest is 5% per year. How much interest she earn in 2 years?

Please explain how did you get it.

Step-by-step explanation:

P = $ 30

r (rate of interest) = 5%

t (no. of years = 2 years

Simple interest = Prt/100

= $3

$32,660

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!
