Basically that’s it but write it down by yourself
The Area of a Square is the square of the measure of one side of the square.
Hence, given the expression for the area of a square, express the given area as the square of an expression to get the measure of one side.
The given expression is:

Rewrite the expression as:

Recall the binomial expansion:

Substituting a=10x and b=8, it follows that the expression becomes:

Since the area of a square is the square of the measure of one side, it follows that the measure of one side from the given expression is 10x-8.
Answer:
(Since polinomial functions are continuous)
(As this quadratic function has an absolute minimum, represented by its vertex)
Step-by-step explanation:
Graphically speaking, quadratic functions are represented by parabolas. In this case, we have a parabola in factorized form. From Theory of Functions, we get that domains of function represents the set of values of
so that exist an image, whose set is known as range is represented by values of
.
is represented by horizontal axis in the figure, whereas
is represented by the vertical axis. By using this approach we get that domain and range of the function are, respectively:
(Since polinomial functions are continuous)
(As this quadratic function has an absolute minimum, represented by its vertex)
The associative property never works with subtraction.
For example:
2 - (7-8) <span>≠ (2-7) - 8
2-(-1)=3, but (-5)-8=-13
</span>
Answer: (B) -2, (E) 1, (F) 2
<u>Step-by-step explanation:</u>
x³ - x² - 4x + 4
= x²(x - 1) - 4(x - 1)
= (x² - 4) (x - 1)
= (x - 2)(x + 2)(x - 1)
Set each factor equal to zero to find the roots:
x - 2 = 0 x + 2 = 0 x - 1 = 0
x = 2 x = -2 x = 1
