Iknow what to do but me with the rounding: )

My teachers taught me a cute poem that might help you
Find your number
Look next door
Five or More
Raise the score
4 or less let it rest
Numbers to the left stay the same
Numbers to the right
Zeros your name

The answer is 4.6 because the number is more than 5 so you raise the score

The answer would be 4.60 because 56 is closer to 60, not 50, so the answer would be 4.60

Ithink the answer is c

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!
