The value of the shortest of the four side lengths of the quadrilateral is 30 cm
What is the length of the shortest side of the quadrilateral?The perimeter of a quadrilateral is the sum of all the sides.
Perimeter of the Quadrilateral = 132 centimeters
Let
The shortest side = x
Since, the sides are consecutive even integers;
Second side = (x + 2)
Third side = (x + 4)
Fourth side = (x + 6)
Perimeter of the Quadrilateral = shortest side + Second side + Third side + Fourth side
132 = x + (x + 2) + (x + 4) + (x + 6)
132 = x + x + 2 + x + 4 + x + 6
132 = 4x + 12
132 - 12 = 4x
120 = 4x
divide both sides by 4
x = 120/4
x = 30 centimeters
Therefore,
Second side = (x + 2)
= 30 + 2
= 32 cm
Third side = (x + 4)
= 30 + 4
= 34 cm
Fourth side = (x + 6)
= 30 + 6
=36 cm

How to complete the table of this absolute function?Based on the information provided, we have the following absolute function:
f(x) = |-2x + 4|
When x = 6, the value of the absolute function is given by;
f(6) = |-2(6) + 4|
f(6) = |-12 + 4|
f(6) = |-8|
f(6) = 8
When x = -1, the value of the absolute function is given by;
f(-1) = |-2(-1) + 4|
f(-1) = |2 + 4|
f(-1) = |6|
f(-1) = -6.
When the value of the absolute function y = 4 is given by;
4 = |-2x + 4|
±4 = -2x + 4
2x = 4 ± 4
2x = 8
x = 4 or 0.
When the value of the absolute function y = 14 is given by;

Shauna says that 2x2 + x - 12 is the same as (x+4)(x-3). Is
she correct? Are the two expressions equal? Explain your
answer.
Answer:
Shauna is incorrect, because (x + 4)(x - 3) is NOT equivalent to 2x² + x - 12
Step-by-step explanation:
Check if she is correct by expanding (x + 4)(x - 3), with FOIL:
(x + 4)(x - 3)
x² - 3x + 4x - 12
x² + x - 12
So, Shauna is incorrect, because the two expressions are not equal.
(x + 4)(x - 3) is equivalent to x² + x - 12, NOT 2x² + x - 12.

What is the value of aaa when we rewrite 6^{x}6 x 6, start superscript, x, end superscript as ax4 ?

What is logarithm?A logarithm is a mathematical function that describes the relationship between a number and its exponent. It is the inverse operation of exponentiation. Logarithms are typically written as log base b, where b is the base of the logarithm and is a positive number.
The logarithm of a number x to base b is denoted as [tex]logb(x)[/tex] and it is the exponent to which we need to raise the base b in order to get the number x.
For example, if we are given [tex]log10(100) = 2[/tex], this means that [tex]10^2 = 100[/tex].
The equation [tex]6^x * 6 * 6[/tex] can be rewritten as [tex]6^x * 6^2[/tex].
To convert 6^x to ax form, we need to take the logarithm of both sides of the equation:
[tex]log(6^x) = log(6^2)[/tex]
And we can simplify the equation as:
[tex]xlog(6) = 2log(6)[/tex]
So, the value of a is log(6) and the value of x is 2.
Therefore, the equation can be rewritten as:
[tex]ax^4 = (log(6))(2^4)[/tex]
Therefore, [tex]a = log(6)\ and\ x=2[/tex]

Step-by-step explanation: To solve this equation, you'll need to use the order of operations to determine the correct sequence of steps to follow. The order of operations is a set of rules that specifies the order in which calculations should be performed in a math problem. It helps to prevent ambiguity and ensures that all calculations are performed consistently.Here is the order of operations:Perform any calculations inside parentheses or brackets first.Perform all multiplications and divisions, working from left to right.Perform all additions and subtractions, working from left to right.Using this order, we can solve the equation as follows:3.5 x 4 + 11 x 2.2 = 14 + 11 x 2.2
3.5 x 4 + 11 x 2.2 = 14 + 24.2
3.5 x 4 + 11 x 2.2 = 38.2Therefore, the solution to the equation is 38.2.

How do you simplify 3 Way ratios?
To simplify 3 ratios, divide each part of the ratio with the same amount and keep diving numbers in the ratio until they are as small as possible but they remain as whole numbers.
To simplify or reduce a fraction, first, we need to find a common factor between the ratio numbers. When we have multiple ratio numbers, we must find a common factor between all of them.
The greatest factor between all the ratio numbers (greatest common factor) will be utilised to divide or reduce the ratios down to their lowest form.
For example reduce the ratio 225: 125: 25
The first step is to determine a common factor between all of the ratio numbers. In this example, we can see that all of the numbers end in either 5 or 0. This means that each number should have 5 as a factor.
If numbers are large and we are not sure of the greatest common factor between them all, we can reduce by a common factor and then reduce again.
Now divide each number by 5 and see what we get.
225/5: 125/5: 25/5
45: 25: 5
When we divide each one by 5 again, we can see that each number again ends in 5 or 0 which means that 5 is still a factor of each number.
Now divide each number by 5 again and get a final ratio of 9: 5: 5.
45/5: 25/5: 5/5
9: 5: 1

if the perimeter of the rectangle was known to be 90 in what would the value of x be in order for this to be true
Answer:

Step-by-step explanation:
length of rectangle is (2/3)x + 10; width is (1/3)x + 5;
perimeter is 90 in; find x:
P = 90 in = 2(2/3)x + 2(10) + 2(1/3)x + 2(5), or
90 in = (6/3)x + 30 in

A statistics content developer at Aplia wanted to know whether study skills are related to memory quality. She invited student volunteers to perform an online memory task. The students saw a list of 60 words and were then asked to recognize a list of five brand new words that are related to words that were on the original list. Students were also asked to provide their GPAs. Consider the following data set, which was collected from student volunteers in 2009. The table gives the frequency for the number of incorrectly identified related words. Use the dropdown menus to complete the table by filling in the missing values for the proportions and percentages
The proportion and percentage is as follows;
[tex]$\begin{array}{cccc}\text { Score Interval } & f & \text { Proportion } & \text { Percentage } \\ 9-10 & 29 & 0.19 & 19 \% \\ 7-8 & 53 & 0.34 & 34 \% \\ 5-6 & 50 & 0.32 & 32 \% \\ 3-4 & 22 & 0.14 & 14 \% \\ 1-2 & 1 & 0.01 & 1 \%\end{array}$[/tex]
What is the difference between proportions and percentages?A percentage represents a ratio or fraction with a denominator that is always 100 as opposed to a proportion, which asserts the equivalent of two ratios or fractions.
Given
[tex]$\begin{array}{cccc}\text { Score Interval } & f & \text { Proportion } & \text { Percentage } \\ 9-10 & 29 & 0.19 & 19 \% \\ 7-8 & 53 & & \\ 5-6 & 50 & & \\ 3-4 & 22 & 0.14 & 14 \% \\ 1-2 & 1 & 0.01 & 1 \%\end{array}$[/tex]
To estimate the total frequency:
Total = sum f
Total = 29 + 53 + 50 + 22 + 1
Total = 155
The proportion (p) exists calculated by:
[tex]$p = \frac{f}{\text { Total }}[/tex]
The percentage (P) exists calculated by:
P = p × 100 %
For interval 7 - 8, we have:
p = 53 / 155 = 0.34
P = 0.34 × 100 % = 34 %
For interval 5 - 6, we have:
p = 50 / 155 = 0.32
P = 0.32 × 100 % = 32 %
So, the complete table is:
[tex]$\begin{array}{cccc}\text { Score Interval } & f & \text { Proportion } & \text { Percentage } \\ 9-10 & 29 & 0.19 & 19 \% \\ 7-8 & 53 & 0.34 & 34 \% \\ 5-6 & 50 & 0.32 & 32 \% \\ 3-4 & 22 & 0.14 & 14 \% \\ 1-2 & 1 & 0.01 & 1 \%\end{array}$[/tex]

Answer:

Step-by-step explanation:
Hope this helps :)
Edwin missed 1 question on the quiz.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
If Edwin got 95% of the questions right on a quiz and there were 20 questions in total, we can calculate the number of questions he missed by finding 5% of the total number of questions.
First, let's find 5% of 20:
= 5% of 20
= (5/100) x 20
= 1 x 20 / 100
= 20 / 100
= 0.2
Since we can't have a fraction of a question, we round the decimal up to the nearest whole number.
In this case, 0.2 rounds up to 1.
