James school is four blocks away from his house if he walks to and from school each day how many blocks will he walk in two weeks

to an from school is 4+4 = 8 blocks

assuming 5 days of school in a week

2 weeks = 10 days

10 days * 8 blocks = 80 blocks

80 blocks

If he walks to and from that 4x2=8 blocks a day.

If he walks for 2 weeks, there are 5 days in a school week, 5x2=10 days.

8x10=80 blocks in 2 weeks.

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!
