How do i find the difference between two different times e. g 13: 40 and 17: 15

You find their difference, of course!

E.g. 17:15 - 13:40 = 3:35/ 3 hrs 35 min.

Just remember that a full hour (1:00) is 60 minutes (0:60). You would never write anything as 0:60, though! Anything over 0:59 becomes 1:00 + the remaining number of minutes.

Hope this wasn't too confusing! Practice makes it easier to handle and understand, so try it out! Hope this helps :)

Hello!

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

why?

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 is true.explanationconditional statements only becomes false when p is true and f is false.
