Express p in terms of q if
Irina-Kira [14]

p=x^2+\dfrac{1}{x^2}\\\\p=\dfrac{x^4}{x^2}+\dfrac{1}{x^2}\\\\p=\dfrac{x^4+1}{x^2}\qquad(*)

q=x+\dfrac{1}{x}\\\\q=\dfrac{x^2}{x}+\dfrac{1}{x}\\\\q=\dfrac{x^2+1}{x}\qquad\text{square both sides}\\\\q^2=\left(\dfrac{x^2+1}{x}\right)^2\\\\q^2=\dfrac{(x^2+1)^2}{x^2}\qquad\text{use}\ \ (a+b)^2=a^2+2ab+b^2\\\\q^2=\dfrac{(x^2)^2+2(x^2)(1)+1^2}{x^2}\\\\q^2=\dfrac{x^4+2x^2+1}{x^2}\\\\q^2=\dfrac{x^4+1}{x^2}+\dfrac{2x^2}{x^2}\\\\q^2=\dfrac{x^4+1}{x^2}+2\qquad\text{subtract 2 from both sides}\\\\q^2-2=\dfrac{x^4+1}{x^2}\\\\\text{From (*) we have}\\\\\boxed{p=q^2-2}

A classmate said that AB &amp; DC are complementary and parallel based on the diagram below. Explain your classmate's error. Not
Ugo [173]

Your classmate's error about AB and DC being complimentary and parallel is that they misapplied the alternate angle property.

<h3>Why are AB and DC not parallel?</h3><h3 />

There isn't enough evidence presented in the diagram to say that AB and DC are parallel.

The evidence required would be proof that angle AWZ is equal to angle WZY.

Instead, all we have is that  angle AWZ and angle XYC are equal which does not tell us what we need to know about AB and DC being parallel.
