Sally and joan have been competing to see who can get more steps in each week on their pedometers. during the past week sally has done 65,723 steps and joan has done 90,345. sally is getting tired of losing and so she says that she actually walks more if you look at actual distance. her stride length length is 5.5 inches longer than joans 18 inch stride. if sally walks 70,000 steps next week, how many more steps than sally does joan have to do to make sure she walks furthest distance next week?

step-by-step explanation:

what does 'mandy have ben 780 bottle caps. ' mean?

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!
