In other meaning, a quadrilateral is a kind of polygon in which four sides for example rectangle, square, and parallelogram are quadrilateral.
a quadrilateral is a four-sided polygon, having four edges and four corners
A parallelogram is a basic quadrilateral with two sets of parallel sides.
The confronting or opposing sides and the opposing angles of a parallelogram are of equal length.
A quadrilateral is a quadrilateral because it has four sides not because it is quadrilateral so it has four sides.
For example, 4 sides are equal so the square is not due to the square all lines will same.
Hence If a shape has four sides, then it is a quadrilateral.

perimeter is 141, What is the length of the base?
Answer:
[tex]Base = 57[/tex]
Step-by-step explanation:
Given
[tex]Length = 2x + 4[/tex]
[tex]Base = 3x[/tex]
[tex]Perimeter = 141[/tex]
Required
Determine the length of the base
The perimeter of an isosceles triangle is:
[tex]Perimeter = 2*Length + Base[/tex]
[tex]141 = 2 (2x + 4) + 3x[/tex]
[tex]141 = 4x + 8 + 3x[/tex]
Collect Like Terms
[tex]4x + 3x = 141 - 8[/tex]
[tex]7x = 133[/tex]
Divide both sides by 7
[tex]x = 19[/tex]
To get the base, we substitute 19 for x in [tex]Base = 3x[/tex]
[tex]Base = 3 * 19[/tex]
[tex]Base = 57[/tex]
Nine times a number, diminished by 4, is 95
Answer:
the number is 11
Step-by-step explanation:
"Diminished" is another word for subtraction, so our equation is : 9x - 4 = 95
Add 4 on each side: 9x = 99
Divide each side by 9: x = 11
I hope this helped, please mark Brainliest, thank you!
Answer:
Step-by-step explanation:
Let a number be X
So
Nine times a number, diminished by 4, is 95
9x-4=95
9x=95+4
9x=99
X=99/9
X=11
So the number is 11

Answer:
3 + 2b
Step-by-step explanation:
To simplify, you have to combine (add) like terms. The like terms are 5 and -2 because they both do not have a variable.
5 + (-2) = 3
2b stays the same because there are no like terms for it.
3 + 2b

Write the ratio 150:450 in the form 1:n
Answer:
1 : 3
Step-by-step explanation:
Given
150 : 450 ( divide both parts by 150 )
= 1 : 3
The ratio 150:450 in the form 1:n will be 1 : 3.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given ratio, 150:450
150/450 = 15/45 = 1/3 = 1:3
Hence "The ratio 150:450 in the form 1:n will be 1 : 3".

QUICK! how do i do this i need the x and y this is the Systems of equations with substitution
Answer:
x=1/15 y = -4 1/3
Step-by-step explanation:
First combine like terms.
-3y = 13
y= -13/3
y= -4 1/3
Substitute for y in next equation
-4 1/3 = 5x - 4
5x = 4 1/3 - 4
5x = 4 1/3 - 4
5x = 1/3
x = 1/3 divided by 5
Since fractions can't be divided, multiply by the inverse
x = 1/3 times 1/5 = 1/15
In a company, 70% of the workers are men. If 1,620 people work for the company who aren't men, how many workers are there in all?
Answer:
2106!
Step-by-step explanation:
1,620 - 70% = 486
486 + 1,620 = 2106
( お力になれて、嬉しいです！)
Answer:
5,400 total workers
Step-by-step explanation:
70% of workers are men, this means that 30% of workers aren't men
This means that 1,620 is 30% of the total workers
To figure out the total workers you do:
30 (percentage that represents the value)/100 = 1,620 (value) / x (total workers)
You then cross-multiply the equation by multiple the numbers diagonal each other:
30/100
=1,620/x
So, 30x = 162,000
You then isolate the variable
30x/30 = 162,000/30
x = 5,400

Answer:
(1,1) and (7,5) => Slope: 2/3
(1,1) and (5,7) => Slope: 3/2
(2,5) and (-1,2) => Slope:1
(2,5) and (-7,-4) => Slope:1
Step-by-step explanation:
The slope of a line is denoted by m and is given as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Calculating the slope one by one for each pair.
(1,1) and (7,5):
Let m1 be the slope of this line
Here
(x1,y1) = (1,1)
(x2,y2) = (7,5)
Putting values in formula
[tex]m_1 = \frac{5-1}{7-1}\\= \frac{4}{6}\\=\frac{2}{3}[/tex]
(1,1) and (5,7):
Let m2 be the slope of this line
Here
(x1,y1) = (1,1)
(x2,y2) = (5,7)
Putting values in formula
[tex]m_2 = \frac{7-1}{5-1}\\m_2=\frac{6}{4} = \frac{3}{2}[/tex]
(2,5) and (-1,2):
Let m3 be the slope of this line
Here
(x1,y1) = (2,5)
(x2,y2) = (-1,2)
Putting values in formula
[tex]m_3 = \frac{2-5}{-1-2}\\m_3 = \frac{-3}{-3} = 1[/tex]
(2,5) and (-7,-4):
Let m4 be the slope of this line
Here
(x1,y1) = (2,5)
(x2,y2) = (-7,-4)
Putting values in formula
[tex]m_4 = \frac{-4-5}{-7-2}\\m_4 = \frac{-9}{-9} = 1[/tex]
Hence,
The points and their respective slopes are as follows:
(1,1) and (7,5) => Slope: 2/3
(1,1) and (5,7) => Slope: 3/2
(2,5) and (-1,2) => Slope:1
(2,5) and (-7,-4) => Slope:1

Avery and Nolan's baseball teams are fundraising. Avery's team has reached ⅗ of their goal. Nolan's team has reached 5/9 of their goal. Avery says her team collected more money than Nolan's team. Both of the goals are $450. Is Avery correct?
Answer:
Yes , Avery is correct
Step-by-step explanation:
To check if Avery is correct, we need to know the exact value obtained in each of their goals
For Avery’s team;
3/5 * 450 = $270
For Nolan’s team
5/9 * 450 = $250
Since $270 is greater than $250, we can see that Avery’s team collected more money
Write an informal proof to show triangles ABC and DEF are similar. Please don’t answer if you don’t know!!
Answer:
ΔABC ~ ΔDEF
Step-by-step explanation:
If the given triangles ΔABC and ΔDEF are similar,
Their corresponding sides will be proportional.
[tex]\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}[/tex]
By substituting the measures of the given sides,
[tex]\frac{4}{2}=\frac{6}{3}=\frac{2}{1}[/tex]
2 = 2 = 2
Since, corresponding sides of both the triangles are proportional, both the triangles will be similar.
ΔABC ~ ΔDEF
