For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

Where:
a: It is the length of the rectangle
b: It is the width of the rectangle
According to the problem data we have to:

Substituting:

We clear "a":

Thus, the length of the fabric is 
ANswer:
The length of the fabric is
F(x) = 7/x
g(x)=x²+10
Then f(g(x))= 7/(x²+10)
By the way g(f(x))=(7/x)² + 10
Hi Jessicaprado539!
The constant proportionality of this equation would be the value that relates the two amounts. In this case, that would be 2/3
Answer:
1227 is correct ................................................
Step-by-step explanation:
Finding the slope using two points:
The formula for slope is
In this case...
^^^Plug these numbers into the formula for slope...

0
^^^This is your slope
If your slope is zero that means that the graph will be horizontal
Hope this helped!
