The answer is 28 because the greatest common factor is 2 so you would do (14 multiplied by 4)/2 and then after multiplying it would be 56 so you divide 56 by 2 and that gives you 28

Given the following functions f(x) and g(x), solve f[g(6)]. f(x) = 6x + 12 g(x) = x − 8
iogann1982 [59]

Answer:

Answer:

Option 2nd is correct.

=0.

Step-by-step explanation:

Given the function:

Solve:

First calculate:

f[g(x)]

Substitute the function g(x)

Replace x with x-8 in the function f(x) we get;

The distributive property says that:

Using distributive property:

⇒

Put x = 6 we get;

Therefore, the value of   is 0.

It takes William 45 minutes to weed the garden. It takes his younger sister May 75 minutes to do the same job. If they work toge
marshall27 [118]

Answer:

B. 28 minutes

Step-by-step explanation:

According to the given statement,

William weeds the whole garden in 45 minutes, then in one minute he will weed 1/45 of the garden

and

similarly, 1/75 of the garden in one minute.

When they both will work together, they will weed (1/45+1/75) of the garden in one minute

Solving the equation:

= \frac{1}{45}+ \frac{1}{75}\\= \frac{75+45}{3375}\\ =\frac{120}{3375}\\ = 0.036

Garden weeded in one minute by both = 0.036

So, number of minutes to weed whole garden = 1/0.036

= 27.77 minutes

Rounding off will give us: 28 minutes

So,

Option B is the correct answer ..

If f(x) and g(x) are polynomial functions, what is the domain of f(x) + g(x) ?
IRINA_888 [86]

Answer:

all real numbers or (-\infty, \infty)

Step-by-step explanation:

since both f(x) and g(x) are polynomials, neither of them have restrictions on their domains. Since they can be defined for all real numbers. It's not like the square root which has a domain of (0, infinity), or log x which is defined only from (0, infinity). So adding these two polynomials would result in a domain of all real numbers.

The base of a triangle measures (3x − 6) units and the height measures (2x + 4) units. Part A: What is the expression that repre
Anettt [7]

To answer this item, we use the equation given for the calculation of the area of the triangle.

                                A = 0.5bh

Substituting the known expressions,

                      A = (0.5)(3x – 6)(2x + 4)

 

Part A: Use distribution method to simplify the expression for the calculation of area.

 

                         A = 0.5(6x^2 + 12x – 12x – 24)

                           A = 0.5(6x^2 – 24)

<span>                          A = 3x^2 – 12</span>

 Part B: The equation for area of has a degree of two because the highest exponent is 2.

<span>Part C: The closure property of polynomials is always closed for multiplication.</span>
