Proof

To form a Pythagorean triple, the three values must satisfy the Pythagorean theorem:

a^2+b^2=c^2\\77^2+420^2=427^2\\5929+176400=182329\\182329=182329

which they indeed do, therefore the numbers 77,420,427 form a Pythagorean triple.

To prove it, you can use the Pythagorean theorem and plug in the numbers. If it equals the same number on both sides it is a Pythagorean triple.

a² + b² = c² (c is the hypotenuse or the longest side/length)

77² + 420² = 427²

5929 + 176400 = 182329

182329 = 182329

It is a Pythagorean triple

Answer:

\large\boxed{\dfrac{x^3+6x}{80x+64}}

Step-by-step explanation:

\dfrac{\frac{1}{8}+\frac{x+4}{16}}{\frac{x+4}{x^2}+\frac{4}{x}}=\left(\dfrac{1\cdot2}{8\cdot2}+\dfrac{x+4}{16}\right):\left(\dfrac{x+4}{x^2}+\dfrac{4\cdot x}{x\cdot x}\right)\\\\=\left(\dfrac{2}{16}+\dfrac{x+4}{16}\right):\left(\dfrac{x+4}{x^2}+\dfrac{4x}{x^2}\right)=\dfrac{2+x+4}{16}:\dfrac{x+4+4x}{x^2}\\\\=\dfrac{x+6}{16}:\dfrac{5x+4}{x^2}=\dfrac{x+6}{16}\cdot\dfrac{x^2}{5x+4}=\dfrac{(x+6)(x^2)}{(16)(5x+4)}\\\\\text{use distributive property}\ a(b+c)=ab+ac

=\dfrac{(x)(x^2)+(6)(x)}{(16)(5x)+(16)(4)}=\dfrac{x^3+6x}{80x+64}
