We have
                             3 / (x-5) - x/5
We make the GCF and we have
                                    15/[ 5(x-5) ] - x(x-5)/[ 5(x-5)]
                                  = [ 15 - x(x-5) ] [5(x-5)]
                                  = [ 15 - x^2 + 5x] / [ 5 (x-5) ]
                                  = [15 - x^2 + 5x]/[5x - 25]
An answer to your question is (15-x^2+5x)/(5x-25)

Archy [21]

Answer:

8 pictures

Step-by-step explanation:

Given

$Window = 5\frac{3}{4}ft$

$Wall = 9.75ft$

$Pictures = 6\ inches$

Required

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

$Space = Wall - Window$

$Space = 9.75 - 5\frac{3}{4}$

Convert fraction to decimal

$Space = 9.75 - 5.75$

$Space = 4ft$

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

$Number = \frac{Space}{Pictures}$

$Number = \frac{4\ ft}{6\ in}$

Convert feet to inches

$Number = \frac{4 * 12\ in}{6\ in}$

$Number = \frac{48\ in}{6\ in}$

$Number = \frac{48}{6}$

$Number = 8$

<em>Hence, 8 pictures can fit the wall</em>
