Would this expression:
Ratling [72]

The given expression is a perfect square trinomial.

<h3>How to classify the given expression?</h3>

Here we have the expression:

(x^2 - 16)^2

Notice that we can rewrite it as:

(x^2 - 4^2)^2

Then we can see that inside the parenthesis we have a difference of squares, but it is squared, so if we define:

x^2 = a\\4^2 = b

We will have:

(a - b)^2 = a^2 + -2ab + b^2 = (x^2)^2 - 2*(4^2)*(x^2) + (4^2)^2

Which is in fact, a perfect square trinomial.

A scale drawing has a scale of 1/4in:12ft. Find the length on the drawing for each actual length. 15 ft.
leonid [27]
So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.

so, what would it be for an actual 15 feet on the drawing then?

\bf \begin{array}{ccll}&#10;\stackrel{inches}{drawing}&\stackrel{feet}{actual}\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;\frac{1}{4}&12\\\\&#10;d&15&#10;\end{array}\implies \cfrac{\quad \frac{1}{4}\quad }{d}=\cfrac{12}{15}\implies \cfrac{\quad \frac{1}{4}\quad }{\frac{d}{1}}=\cfrac{12}{15}&#10;\\\\\\&#10;\cfrac{1}{4}\cdot \cfrac{1}{d}=\cfrac{12}{15}\implies \cfrac{1}{4d}=\cfrac{12}{15}\implies 15=48d\implies \cfrac{15}{48}=d\implies \cfrac{5}{16}=d
