On a tractor, the diameter of the large tire is 5 feet and the diameter of the small tire is 3 feet 9 inches. A sketch is given.
5 feet
3 ft 9 in
A toy tractor is made to scale from the actual tractor. On the toy tractor, the diameter of the large tire
is 8 inches. What is the diameter, in inches of the small tire on the toy tractor?

sorry man i accidentally pressed yes my bad

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!

my computer is slow i can not see it sorry
