The value of x<em> </em>in the polynomial fraction 3/((x-4)•(x-7)) + 6/((x-7)•(x-13)) + 15/((x-13)•(x-28)) - 1/(x-28) = -1/20 is <em>x </em>= 24
<h3>How can the polynomial with fractions be simplified to find<em> </em><em>x</em>?</h3>
The given equation is presented as follows;

Factoring the common denominator, we have;

Simplifying the numerator of the right hand side using a graphing calculator, we get;
By expanding and collecting, the terms of the numerator gives;
-(x³ - 48•x + 651•x - 2548)
Given that the terms of the numerator have several factors in common, we get;
-(x³ - 48•x + 651•x - 2548) = -(x-7)•(x-28)•(x-13)
Which gives;

Which gives;

x - 4 = 20
Therefore;

The dimension of the parallelogram ABCD will be 14 inches, 48 inches, 14 inches and 48 inches.
<h3>What is a parallelogram?</h3>
It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
The perimeter of a parallelogram is 76 inches.0
And one side measure is 14 inches.
Then the rest of the sides will be
We know that opposite sides are prallel and equal.
Let ABCD is a parallelogram.
AB = CD = 14 inches
BC = AD = x
Then the value of x will be
We know
P = 2(AB + BC)
76 = 2(14 + x)
x = 48

add the numerators: 
simplify the fraction by dividing 45 by 8: 5 
8. 3 x 6 = 18
5 x 6 = 30
7 x 6 = 42
9 x 6 = 54
therefore, y = 6x
9. 5:7 is similar to 8:L
divide 8 by 5: 1 
multiply 7 by 1
: 11 
L = 11
inches
10. 5 - 2x = 29
subtract 5 from each side: -2x = 24
divide each side by -2: x = -12
11. fruit = 15%
15% = 15/100
simplify by dividing by 5: 
12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.
