Simply add 13 to both sides and divide by 4, and then square root both sides. Remember, square rooting will give you a positive and negative value for k.

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.

How to find square feet
Alex73 [517]
In order to find a square feet, you must evaluate the area of a specific shape. Then, you must apply the shape’s formula for area.
Examples:


Rectangle: lw or Length x Width


Circle: pi x r^2 or 3.14159... x radius squared


Triangle: 1/2 bh 1/2 base x height

Give two different sequences of three transformations that would map PQR onto EFG given that PQR=EFG.
Gre4nikov [31]

9514 1404 393

Answer:

  1. Translate P to E; rotate ∆PQR about E until Q is coincident with F; reflect ∆PQR across EF
  2. Reflect ∆PQR across line PR; translate R to G; rotate ∆PQR about G until P is coincident with E

Step-by-step explanation:

The orientations of the triangles are opposite, so a reflection is involved. The various segments are not at right angles to each other, so a rotation other than some multiple of 90° is involved. A translation is needed in order to align the vertices on top of one another.

The rotation is more easily defined if one of the ∆PQR vertices is already on top of its corresponding ∆EFG vertex, so that translation should precede the rotation. The reflection can come anywhere in the sequence.

__

<em>Additional comment</em>

The mapping can be done in two transformations: translate a ∆PQR vertex to its corresponding ∆EFG point; reflect across the line that bisects the angle made at that vertex by corresponding sides.
