What is mathematical expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mathematical expression is,
⇒ √x + 20 = 9
Now,
Solve the expression for the value of x as;
The mathematical expression is,
⇒ √x + 20 = 9
Take square on both side, we get;
⇒ (√x + 20 )² = 9²
⇒ x + 20 = 81
Subtract 20 both side, we get;
⇒ x + 20 - 20 = 81 - 20
⇒ x = 61
Therefore, The value of x will be 61.

A four-digit perfect square number is created by placing two positive two-digit perfect square numbers next to each other. What is the four-digit square number?
Answer:
1681
Step-by-step explanation:
In a four digit perfect square, the first two digits and last two digits taken seperately are also perfect squares.
Therefore, the answer is 1681 because 1681=41*41 and
16=4*4 and 81=9*9

PLEASE HELP!! solve |2x-2| ≥6.
x ≤ -2 OR x ≥ 4
__________________________________________________________
Step-by-step explanation:We are given the inequality:
|2x - 2| ≥ 6
Getting rid of the Modulus:
Since 2x-2 is in modulus:
|2x-2| = -(2x-2) OR 2x-2
(since the modulus of both these values is 2x-2)
Hence, our inequality can be written in 2 different ways:
2x-2 ≥ 6 (if 2x-2 ≥ 1)-(2x - 2) ≥ 6 (if 2x-2 < 0)__________________________________________________________
Solving these 2 inequalities:
Solving inequality 1:
2x - 2 ≥ 6
2x ≥ 8 [adding 2 on both sides]
x ≥ 4 [dividing both the sides by 2]
This is the solution of the inequality if: 2x-2 ≥ 0
Solving Inequality 2:
-(2x-2) ≥ 6
It can be rewritten as:
2 - 2x ≥ 6
2 ≥ 6 + 2x [adding 2x on both the sides]
-4 ≥ 2x [Subtracting 6 from both sides]
x ≤ -2 [Dividing both sides by 2]
This is the solution of the given inequality if: 2x-2 < 0
__________________________________________________________
Solution of the given Inequality:
Therefore, the solution of the given inequality |2x-2| ≥ 6 are:
x ≥ 4 (if 2x-2 ≥ 0)
x ≤ -2 (if 2x-2 < 0)
Hence, option C is correct!

What is the domain of the square root function graphed below?
Answer:
The domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.
Step-by-step explanation:
From the graph, it is clear that the graph is heading towards positive infinity from x=-4.
The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.
i.e. [-4, ∞)
Hence, the domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.

If the parallel lines m and n are 6 units apart, how many units of translation is equivalent to the composition of two reflections over lines m and n?
9514 1404 393
Answer:
12 units
Step-by-step explanation:
Reflection over two lines x units apart is equivalent to a translation of 2x units. Since the given lines are 6 units apart, ...
the equivalent translation is of 12 units.
___
Example:
Lines at x=0 and x=6. Point (x, 0). After reflection over x=0, the point is located at (2·0 -(x), 0) = (-x, 0). After reflection of that over x=6, the point is located at (2·6 -(-x), 0) = (12 +x, 0). That is, 12 has been added to the x-coordinate, meaning the point was translated 12 units. (The translation is in the direction the second line is from the first.)

Answer:
Price is $1088 (agrees with answer B)
Step-by-step explanation:
Notice that the linear equation that represents this relationship can be estimated via finding the slope and y-intercept using a couple of the given points on the plane (for example (5, 140), and (10, 200), which results in;
Price = 12 x + 80
where "x" is the number of computers shipped.
Then, to ship 84 computers, we have the following price:
Price = 12 (84) + 80 = 1088
Then the price is $1088.

Answer:
Step-by-step explanation:
tan 26° = [tex]\frac{x}{90}[/tex] ⇒ x = 90tan26° ≈ 43.9 ft. (This answer for the picture)
sin 26° = [tex]\frac{h}{100}[/tex] ⇒ h = 100sin26° ≈ 43.9 ft (This answer for the text)
h = √(100² - 90²) ≈ 43.589 ft. (Pythagorean theorem)
