Given the following venn diagram, choose the correct set for m ∩ n. {3, 9} {2, 5, 9} {4, 7}

M ∩ N means the intersection of M and N, so they are looking for the numbers that are in both M and N.

The numbers that are in both are 4 and 7

The answer is {4,7}

M ∩ N = { 4,7}

Step-by-step explanation:

M ∩ N

This means intersection, or where M and N overlap

M = { 3 9 4 7}

N = { 4 ,7 ,6}

M ∩ N = { 4,7}

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!
