In a club, there are four interest
groups:
. sports, Music, Gymnastics and Drama
Each member is in one and only one
interest group. The pie chart represents
the numbers in each group.
Music
Sports
120
Drama
Gymnastics
) There are 80 members in the Sports
group. Calculate the total
membership of the club.
5) What percentage of the total
membership are in the Sports
group?
There are 48 members in the Drama
group. Calculate the size of the
angle marked x®.

step-by-step explanation:

b

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!
