Consider the following polynomial functions: f(m) = (-9 + 5m + 2m2) and gfm) = (6 - m). Which of the following statements about the polynomial functions are true? Select all that apply. A. The expression that represents the difference of the polynomials illustrates that polynomials are closed under subtraction.

B. The difference of f(m) and g(m) can be represented by the expression 2m2 + 4m – 15.

c. The expression that represents the sum of the polynomials is a third degree polynomial.
d. The sum of f(m) and g(m) can be represented by the expression 2m2 + 4m – 3.

e. The product of f(m) and g(m) can be represented by the expression -2m3 + 7m2 +39m – 54.​

step-by-step explanation:

first, eliminate the parenthesis:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
