A rubber band is n inches long. If a child stretches the rubber band, and the new length of the rubber band is 1.24n, which statement is true?
A. 'The length of the rubber band increases by 240% because 1.24n = 1 + 0.24n.
B. The length of the rubber band increases by 24% because 1.24n = n +0.24n
C.
The length of the rubber band increases by 2.4% because 1.24n = 1 +0.24n
D. The length of the rubber band increases by 0.24% because 1.24n = n +0.24

answer: 7

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!
