John goes for a walk and travels 78 of a mile in 14
hour.

Select all of the statements below that are true about the unit rate for John's walk.
A
John travels less than a mile each 14
hour, so he will average about 2
miles per hour.

B
John's unit rate is equal to 78÷14
.

C
John will average 312
miles per hour.

D
John will average 1512
miles per hour.

E
John will walk less than 4
miles per hour because he walks less than 1
mile in 14
hour.

5/20 so 25%

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!

wait this depends wether emily and zach how they are thinking.

yes they are the same.
