For this case we have the following expression:
 -2x ^ 2 (x + 5) + x (2x ^ 2-10x) + x
 Rewriting we have:
 -2x ^ 3 - 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
 Grouping terms with the same exponent:
 x ^ 3 (-2 + 2) + x ^ 2 (-10 - 10) + x
 -20x ^ 2 + x
 Rewriting:
 x (-20x + 1)
 Answer:
 
The simple form of the expression is:
 
x (-20x + 1)

Answer:

x

Step-by-step explanation:

-2x^2(x-5)+x(2x^2-10x)+x

Distribute-2x^2 through parentheses

-2x^3+10x^2+(2x^2-10x)+x

Distribute x through parentheses

-2x^3+10x^2+2x^3-10x^2+x

Eliminate the opposites

-2x^3+2x^3=0 and 10x^2-10x^2=0 both sets of opposites cancel each other out, which leaves us with just x remaining.

The simplest form of of the expression is x.

What happens when you reflect an object over intersecting line( combination of reflection)?
bazaltina [42]

The result concluded is equivalent to a single rotation transformation of the original object.

<h3>Explanation of how reflection across axis works?</h3>

When a graph is reflected along an axis, say x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.

The Compositions of Reflections Over Intersecting Lines states that if we perform a composition of two reflections over two lines that intersect.

The result concluded is equivalent to a single rotation transformation of the original object.

WILL GIVE A BRAINLEST !!!!
givi [52]

Answer: The correct option is second, i.e., x>0.

Explanation:

As we know that the domain is the set of all possible inputs. If function is defined as, f(x) then all possible value of x for which the function f(x) is defined is called domain.

In a graph the domain is defined on the x axis and the range of the function is defined on y-axis.

In the given graph the function is defined from x=0 to x=\infty because for x\leq 0 the graph is not defined. It means for x\leq 0 the function is not defined.

Sicen the graph is defined for all positive values of x, therefore the domain of the function is al real number greater than 0. It can be written as x>0 and the second option is correct.
