Louis joue avec des carreaux gris il dispose ses carreaux pour obtenir des carrés 1/ Si l'on double le côté du carré, double-t-on le nombre de carreaux de la bordure ? 2/ Louis souhaite connaître le nombre de carreaux à prévoir pour n'importe qu'elle carré construit selon le modèle. Comment doit-il s'y prendre ? 3/ Peut-on obtenir une bordure de 100 carreaux ? De 150 ? De 200 ? 4/ Comment savoir tout de suite, si on donne le nombre de carreaux, s'il correspond exactement à un carré ?

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

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!
