Answer:

(l² + 2m²)²

Step-by-step explanation:

l⁴ + 4l²m² + 4m⁴

=(l²)² + 2 x l² x 2m²+ (2m²)²

Now this is in the form of (a + b)² = a² + 2ab + b² so we get

= (l² + 2m²)²

Answer:

see explanation

Step-by-step explanation:

The side of the square = x + 2, thus area is equal to

(x + 2)² ← expand using FOIL

= x² + 4x + 4

Given area = 7 then

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required

The function f(x) = x] is graphed over the interval [-6, 3]. Which translation of the graph has the domain (-3, 6]? 0 A. g(x) =
bezimeni [28]

An interval graph in graphical theory is indeed an undirected graph formed by an interval set just on true line, with a top for every interval as well as an edge between vertex v to intersections. Graph intervals and these graphs are chordal graphs and graphs that are perfect, and the further discussion can be defined as follows:

Given:

\bold{function\ f(x) = |x|}

\bold{Interval \ \[-6, 3\]}

To find:

Domain=?

Solution:

The \bold{function\ f(x) = |x|} is a graphic over the[-6,3] interval.

A<em><u> graph of the domain</u></em> [-3,6 ] is indicated mostly by the <em><u>transformation </u></em>that <em><u>horizontal shifts</u></em> to combat (h(x)=f(x-3)).

\to \bold{h(x) =f(x-3)}

            =|x-3|

Therefore, the final answer is "Option (D)".
