3. Pearl wants to determine the average
number of goals she scored her first five
field hockey games of the season. She
scored 2 goals in the first game, 3 goals
in the second, and 5 goals in the third.
She can't remember how many goals she
scored in the fourth and fifth games but
she does remember that she scored the
same number of times in each of those
games. The expression
2 + 3 + 5 + x + x
will determine the average number of
goals she scored, where x is the number of
goals she scored in each of the fourth and
fifth games.
If Pearl scored 2 goals in each of the
fourth and fifth games, what was her
average number of goals per game?

11

step-by-step explanation:

32.50-7.50=25

225/25=11

about 168 miles

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

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!
