Therefore, as a result square root property can be used to solve a quadratic equation.
Describe equation.
To create an equation, the equal sign is placed between two numerical or variable expressions, as in 4x+9=25.
The answer is a number that may be used in an equation to replace the variable.
According to the given question:
In order to isolate the variable being solved,
the square exponents are removed using the Square Root Property.
The positive and negative values of the number that, when multiplied by itself, equals x are provided by the formula x=±√c x = ± c.
Therefore , as a result square root property can be used to solve a quadratic equation.

Which expression is a factor of 9x^2-4x+1 ( ps ^2 is an exponent)
Answer:
The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Step-by-step explanation:
9x² - 4x + 1 = 0 ax² + bx + c = 0
The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20
b2−4ac < 0, the equation has no real number solutions, it has complex solutions

The measure of ∠ABD is (0.18x+56)° and the measure of ∠CBD is (0.07x+46)°. Find the value of x.
Answer:
x = 312
Step-by-step explanation:
We know that ∠ABD and ∠CBD are supplementary, meaning their measures add up to 180°. We can use this knowledge to put both measures into an equation.
[tex](0.18x+56) + (0.07x+46)= 180[/tex]
Simplify.
[tex]0.18x+56 + 0.07x+46= 180[/tex]
Simplify.
[tex]0.25x + 102 = 180[/tex]
Subtract 102.
[tex]0.25x = 180 - 102[/tex]
Simplify.
[tex]0.25x = 78[/tex]
Divide by 0.25
[tex]x = \frac{78}{0.25}[/tex]
Simplify.
[tex]x = 312[/tex]

The length of three sides of a triangle are 3x+1/2 ,2x+1/4 , and x +1/2 .the perimeter of the triangle is
Answer:
Step-by-step explanation:
Just add the three sides P = side1 + side2 + side3
Don't let the 'x' terms confuse you, they are just numbers times 'x'
P = 3x+1/2 + 2x+1/4 + x+1/2
= 6x + 5/4
P = 6x + 1&1/4

A box contains four equal-sized cards labeled 1 , 3, 5, and 7. Tim will select one card from the box. What is the probability that Tim will select a card labeled 3?
Answer: 1/4
Step-by-step explanation:
Since the box box contains four equal-sized cards labeled 1 , 3, 5, and 7. The probability of selecting any number out of the four numbers will be 1/4 if they are selected once.
If Tim selects one card from the box, the probability that Tim will select a card labeled 3 will be: = 1/4
This is because 3 only occurs once and there are 4 numbers in total.

Answer:
x = 5 units
Step-by-step explanation:
since it is an isosceles triangle, the perpendicular "x" bisects the base (24) into two units of 12.
using the Pythagorean theorem:
x² = 13² - 12² = 169 - 144 = 25
x = √25 = 5

Answer: x=10 and angle RST is 75 degrees
Step-by-step explanation:
For each triangle find the value of x
Answer:
x = 20
Step-by-step explanation:
The sum of the angles in a triangle is 180. A right triangle has one angle of 90. Thus, the sum of the other two angles will be 90. So, 90+31 = 121 and 180-121 = 59. (3x-1) = 59. Solve for x. This would mean that x would be 20. 3*20 = 60 and 60-1 = 59. All the angles add together would get 180: 59+90+31.

A 23.7-foot tall flagpole casts a 42-foot shadow. What is the angle that the sun hits the flagpole? Express your answer in DMS
Answer:
60.6°
Step-by-step explanation:
Using trigonometry :
Opposite = Height of shadow = 42 feets
Adjacent = height of flagpole = 23.7 feets
Tan θ = opposite / Adjacent
Tan θ = height of shadow / height of flagpole
Tan θ = 42 / 23.7
Tan θ = 1.7721518
θ = tan^-1(1.7721518)
θ = 60.56
θ = 60.6°

Samantha and Luis are attempting to dentermine the average number of library books that seventh-grade students check out at one time. Samantha surveys every other seventh grade students
Answer: Your question is incomplete
But if the attached image is the complete question “whose sample is the most random”, then your answer is:
Luis’ sample.
Step-by-step explanation:
A random sample is one where each member is selected at random.
It is the kind of sampling where each member has an equal chance of being selected.
Samantha and Luis are trying to determine the number of library books that seventh graders check out. Their focus is;
1.) Seventh graders and
2.) Library books
Samantha surveys seventh graders leaving the library while Luis surveys seventh graders at random in the school cafeteria.
Samantha’s survey is more focused because each member of her sample was leaving the library meaning that they had handled books.
But Luis’ sample is more random because he takes his survey from all seventh graders (seventh graders in the cafeteria). With his random sampling, there is a high probability that each member never handled library books.
I just don’t get it, please help me.
