The value of x is 1.
DilationDilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
Dimension of parallelogram P 10 and x + 3.
Dimension of parallelogram P' 20 and 8.
To findThe value of x.
How to find the value of x?Lenght of P' = Dilation x Lenght of P
20 = Dilation x 10
Dilation = 2
Then
width of P' = Dilation x width of P
8 = 2 (x + 3)
4 = x + 3
x = 1
So the value of x is 1.

Answer:
45 degrees
Step-by-step explanation:
Vertical angle 105, so we put it on the other side. We then do 105+30+(Angle 1)=180, because all lines add up to 180, and we get angle 1=45
please consider brainliest!
Answer:
45
Step-by-step explanation:
the line will be 180 degrees so we already got 30. Then we have two lines that seem to be vertical so both 105. You add 105+35=135 then 180-135=45
The diagram shows a right-angled triangle.
Use Pythagoras ' Theorem to work out the length of AC.
Answer:
AC = 15.52 centimeters
Step-by-step explanation:
Step 1) Determine the definition of the Pythagorean Theorem.
According to the Pythagorean Theorem, the square of the length of the hypotenuse of any right triangle equals the sum of each of the legs squared.
Step 2) Apply the theorem to the problem.
In this specific situation, AB and BC are the legs of the right triangle, while AC is the hypotenuse. This means that AB^2 + BC^2 should equal AC^2.
Step 3) Create an equation based on the formula.
The equation should look like this:
AB^2 + BC^2 = AC^2
4^2 + 15^2 = AC^2
16 + 225 = AC^2
241 = AC^2
AC = [tex]\sqrt{241}[/tex]
AC = 15.52 centimeters

An equilateral triangle has a perimeter of 12 x 18 units. Which expression can be used to show the length of one side of the triangle? 6 (2 x 3): Each side length is 2 x 3 units. 3 (4 x 6): Each side length is 4 x 6 units. 2 (6 x 9): Each side length is 6 x 9 units. X (12 18): Each side length is 12 18 units.
The expression can be used to show the length of one side of the triangle is 4x+6.
Given
An equilateral triangle has a perimeter of 12 x + 18 units.
What is the perimeter of an equilateral triangle?The perimeter of the Equilateral Triangle is simply the sum of its three sides which are equal in length. Perimeter is denoted by the P symbol.
[tex]\rm Perimeter= 3 \times S[/tex]
Therefore,
The expression that can be used to show the length of one side of the triangle is;
[tex]\rm Perimeter = 12x+18\\\\Perimeter = 3(4x+6)[/tex]
Hence, the expression can be used to show the length of one side of the triangle is 4x+6.

g(x) = 5x4 +38x° +18x² – 22x–7
Answer:
[tex]x=-7,x=-1,x=-0.289898,x=0.689898[/tex]
or [tex]x=-7,x=-1,x=\frac{1}{5}-\frac{\sqrt{6}}{5},x=\frac{1}{5}+\frac{\sqrt{6}}{5}[/tex]
Step-by-step explanation:
Factor by grouping
[tex]g(x)=5x^4+38x^3+18x^2-22x-7\\\\g(x)=5x^4+33x^3-15x^2-7x+5x^3+33x^2-15x-7\\\\g(x)=x(5x^3+33x^2-15x-7)+1(5x^3+33x^2-15x-7)\\\\g(x)=(x+1)(5x^3+33x^2-15x-7)\\\\g(x)=(x+1)(5x^3+35x^2-2x^2-14x-x-7)\\\\g(x)=(x+1)(5x^2(x+7)-2x(x+7)-1(x+7))\\\\g(x)=(x+1)(x+7)(5x^2-2x-1)\\\\0=(x+1)(x+7)(5x^2-2x-1)\\[/tex]
We can easily see that the first two zeroes are [tex]x=-1[/tex] and [tex]x=-7[/tex], however, the third zero will need the help of the quadratic formula:
[tex]0=5x^2-2x-1\\\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(5)(-1)}}{2(5)}\\\\x=\frac{2\pm\sqrt{4+20}}{10}\\ \\x=\frac{2\pm\sqrt{24}}{10}\\ \\x=\frac{2\pm2\sqrt{6}}{10}\\ \\x=\frac{2}{10}\pm\frac{2\sqrt{6}}{10}\\ \\x=\frac{1}{5}\pm\frac{\sqrt{6}}{5}\\\\x_1\approx0.689898\\\\x_2\approx-0.289898[/tex]
Therefore, the zeroes of the function are [tex]x=-7,x=-1,x=-0.289898,x=0.689898[/tex]
Solve for x 3 x − 2 = 4 x + 5
Answer:
3x - 2 = 4x + 5
3x - 4x = 2 + 5 (move the numbers with the variable x to one side, and the normal numbers to the other side. Switch the signs of the numbers you move. 4x became -4x and -2 became 2.)
-x = 7 (simply add the numbers)
x = 7
Solve for x.
4(x−214)=−3.7
Enter your answer as a decimal in the box.
x = ___
Step-by-step explanation:
First we distribute the 4 amongst everything inside the parentheses.
(Remember that when we distribute numbers, we are basically multiplying them.)
So now we have: 4x - 856 = -3.7
Next we do: 856 + (-3.7), and that gives us 852.3
Finally, we divide both sides by 4 in order to isolate the x-value.
Our answer is now x = 213.075

b. Lauren bought a new package of notebook
paper containing 300 sheets. She used
27 sheets in a science notebook. What
percent of the paper did she have left?
272
Answer:
91%Step-by-step explanation:
300 × x/100 = 27=> 3 × x = 27=> x = 27/3=> x = 9This means that 9% of the notebook is used in science.
100% - 9% = Percentage of paper left in notebook.=> 91% = Percentage of paper left in notebook.This means that 91% of the notebook pages is remaining.
The table shows the values of y for different values of x: x 5 7 9 10 11 12 13 y 3 0 −1 −6 3 8 −4 The correlation coefficient for the data is 0. 715. Which statement is true about the data in the table? There is a strong positive relationship between x and y. There is almost no relationship between x and y. There is a strong negative relationship between x and y. There is a weak negative relationship between x and y.
To solve the problem we must know about the correlation coefficients.
What is the correlation coefficient?The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
1 indicates a strong positive relationship.-1 indicates a strong negative relationship.A result of zero indicates no relationship at all, therefore, independent variable.The correlation coefficient 0.715 denotes, "There is a strong positive relationship between x and y".
Given to us
The correlation coefficient for the data is 0.715.As we can see that the value of the correlation coefficient is 0.715, therefore, it is close to 1 means the relationship is strong, while the '+' symbol denotes that the relationship is positive.
Hence, the correlation coefficient 0.715 denotes, "There is a strong positive relationship between x and y".

What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
Given information-
Mrs. Gomes found that 40% of students at her high school take chemistry.
Mrs. Gomes randomly surveys 12 students.
Total number of students who have taken chemistry in surveys is 4.
As the 40 percent of students at her high school take which is equal to the 0.4. Thus the percent of students who is not at her high school, is equal to the,
[tex]=1-0.4\\=0.6[/tex]
As the total number of surveyed students is 12 and the number of chemistry student is 4 in the surveyed students. Thus the probability of this event can be given as,
[tex]=P(1)+P(2)+P(3)+P(4)\\=\sum_{0}^{4}C_r(0.4)^r(0.6)^{12-r}[/tex]
