Answer:

Option (b) is correct.

\Rightarrow x^3(2x+5)-4(2x+5)  is equal to the given polynomial  2x^4+5x^3-8x-20

Step-by-step explanation:

Given polynomial 2x^4+5x^3-8x-20

We have to choose form the given option that is equal to the given polynomial  2x^4+5x^3-8x-20

Consider the given polynomial  2x^4+5x^3-8x-20  

We will factorize the  given polynomial by  grouping like terms.

Taking x^3 common from first two term and -4 common from last two term , we have,

2x^4+5x^3-8x-20  

\Rightarrow x^3(2x+5)-4(2x+5)      

Again taking (2x +5) common from both terms, we get

\Rightarrow (x^3-4)(2x+5)      

Thus, Option (b) is correct.

If you would like to find the equal expression to the polynomial 2x^4 + 5x^3 - 8x - 20, you can do this using the following steps:

2x^4 + 5x^3 - 8x - 20 = x^3 * (2x + 5) - 4 * (2x + 5)

The correct result would be x^3 * (2x + 5) - 4 * (2x + 5).

Find the Y-coordinate of point P that lies 1/3 along segment RS, where R (-7, -2) and S (2, 4).
QveST [7]

Solution:

Given that the point P lies 1/3 along the segment RS as shown below:

To find the y coordinate of the point P, since the point P lies on 1/3 along the segment RS, we have

\begin{gathered} RP:PS \\ \Rightarrow\frac{1}{3}:\frac{2}{3} \\ thus,\text{ we have} \\ 1:2 \end{gathered}

Using the section formula expressed as

[\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}]

In this case,

\begin{gathered} m=1 \\ n=2 \end{gathered}

where

\begin{gathered} x_1=-7 \\ y_1=-2 \\ x_2=2 \\ y_2=4 \end{gathered}

Thus, by substitution, we have

\begin{gathered} [\frac{1(2)+2(-7)}{1+2},\frac{1(4)+2(-2)}{1+2}] \\ \Rightarrow[\frac{2-14}{3},\frac{4-4}{3}] \\ =[-4,\text{ 0\rbrack} \end{gathered}

Hence, the y-coordinate of the point P is
