Answer:

R\left(\frac {4x_1+3x_2}{7} , \frac {4y_1+3y_2}{7}\right)

Step-by-step explanation:

Let the coordinate of the points W, V and R are (x_1,y_1), (x_2,y_2), and (x_s,y_s)respectively.

The coordinate of the section point, (x_s,y_s), which divides the line joining the two points (x_1,y_1) and (x_2,y_2) in the ration m:n is

x_s=\frac {nx_1+mx_2}{m+n} and

y_s=\frac {ny_1+my_2}{m+n}.

The given ration is, m:n=3:4

R(x_s,y_s)=R\left(\frac {nx_1+mx_2}{m+n} , \frac {ny_1+my_2}{m+n}\right)

=R\left(\frac {4x_1+3x_2}{7} , \frac {4y_1+3y_2}{7}\right).

The exact point can be determined by putting the value of the exact coordinate in the above-obtained formula.

The answer is Option B (x + 6)(x^2 + 8)

Step-by-step explanation:

Step 1: Group the given cubic polynomial into two sections.  

So  polynomial can be  grouped as

(x^3 + 6x^2) + (8x + 48)

Step 2:Find what's the common in each section.

In section (x^3 + 6x^2)  the come term is x^2

In section (8x + 48)  the come term is 8

Step 3:Factor the commonalities out of the two terms.

Factoring out x^2 from the first section  (x^3 + 6x^2), we get  x^2(x + 6)

Factoring out 8 from the second section(8x + 48) ,  we will get 8(x + 6).

Step 4: Combine the factors together for terms contains the same factor,

Combining we get,\left(x+6\right)\left(x^2+8\right)

\left(x+6\right)\left(x^2+8\right)

Let b and p represent the distances traveled by baby and pickles, respectively.
.. b +p = 27
.. p = 5(3b -1)

Substituting, you have
.. b +5(3b -1) - 27
.. 16b -5 = 27
.. 16 b = 32
.. b = 2

The baby travel was 2 miles.
The pickles travel was 25 miles.
