What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Using Pythagoras theorem
c² = a² + b²
where c is the hypotenuse.
Here, c² = 3² + 3²
c = 3√2
So, the perimeter of triangle is
= 3 + 3 + 3√2
= 6 + 3√2

18a+15
Answers
Answer: 3(6a+5)
We can confirm this by distributing the 3 back in
3*6a = 18a
3*5 = 15
So 3(6a+5) = 3*6a+3*5 = 18a+15
The process of factoring polynomials like this is basically using the distributive property in reverse.
Answer:
3(6a + 5)
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into 18a and 15?
It is 3.
2 - What is the highest degree of a that divides evenly into 18a and 15.
It is 1, since a s not in every term.
3 - Multiplying the results above,
The GCF is 3.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3 (18a/3 + 15/3)
3) Simplify each term in parentheses.

Answer:
Option D - x = 3 3/5
Step-by-step explanation:
Lets make the left side into an improper fraction :
2 2/5 = 12/5
Now let's make both fraction into equivalent ones but with the same denominator :
2/3 = 10/15
12/5 = 36/15
Now we substitute the equivalent values back into the equation :
10/15 × x = 36/15
Now we multiply both sides by 15 to remove the denominators:
10 × x = 36
Now we divide both sides by 10 and simplify :
x = 36/10
x = 18/5
x = 3 3/5
So our answer will be Option D

Answers
Answer:
b = 9
Step-by-step explanation:
[tex]\frac{2}{3} b + 5 = 20-b\\\frac{2}{3} b+5+b=20-b+b\\\frac{5}{3} b+5=20\\\frac{5}{3} b+5-5=20-5\\\frac{5}{3}b=15\\b= 15*\frac{3}{5} \\b= 9[/tex]
Answer:
[tex]b = 9[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} b + 5 = 20 - b[/tex]
In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.
[tex]\frac{2}{3} b + 5 - 5 = 20 - b - 5[/tex]
Simplify.
[tex]\frac{2}{3} b = 15 - b[/tex]
Add b to both sides.
[tex]\frac{2}{3} b + b = 15 - b + b[/tex]
Simplify.
[tex]\frac{2}{3} b + b = 15[/tex]
Multiply everything by 3 to remove the fractions.
[tex]3(\frac{2}{3}b+b) = 3(15)[/tex]
Simplify.
2b + 3b = 45
Simplify.
5b = 45
Divide 5 from both sides.
5b ÷ 5 = 45 ÷ 5
Simplify.
b = 9

Find the measures of the angles of an isosceles triangle where the ratio of the vertex angle to one of the base angles is 1:2.
Answers
Answer:
Angles of the isosceles triangle are 36°, 72° , 72°
Step-by-step explanation:
Vertex angle : Base angle = 1 : 2
Vertex angle = x
Base angle = 2x
Sum of all angles of a triangle = 180°
x + 2x + 2x = 180°
5x = 180
x = 180 ÷ 5
x = 36°
2x = 2 *36 = 72°
Angles of the isosceles triangle are 36°, 72° , 72°

jeanne barrons has decided to buy a new car. it has a base price of

while surfing the internet, she learned that the dealer's cost is
approximately 83% of the base price and 80% of the price of the options.
what should barrons estimate as the dealer's cost? (section 9-2) *
o a. $19,224.92
b. $17,659.09
c. $17,500.25
d. $19,430.84
Answers
Answer:
a. $19,224.92
Step-by-step explanation:
The dealer's cost will be the sum of the dealer's costs for the base car, its options, and the destination charge.
__
cost for base car = 0.83 × $21,276 = $17,659.08
cost for options = 0.80 × $1,219.80 = $975.84
cost for destination charge = $590.00
The sum of the dealer's costs is ...
$17,659.08 +975.84 +590.00 = $19,224.92
Barrons should estimate the dealer's cost to be $19,224.92.
the distance between dakshes's house and his school is 7 km.how many kilometers does he have travel in 6 days

At a basketball game, 45% of people attending were supporting the home team, while 55% were supporting the visiting team. If 1413 people attending the game supported the home team, what was the total number of people attending the game?
Answers
divide the number of people supporting the home team by the percentage supporting the home team.
1413/0.45 = 3140
total people = 3,140
The total number of people attending the basketball game was 3140.
Let's denote the total number of people attending the game as "T."
According to the information given, 45% of the people were supporting the home team. Therefore, the number of people supporting the home team can be calculated as 45% of the total number of people: 0.45 * T.
We are also told that 1413 people supported the home team. So, we can write the equation:
0.45 * T = 1413
Now, let's solve for the total number of people attending the game (T):
T = 1413 / 0.45
T = 3140
Therefore, the total number of people attending the basketball game was 3140.

Write the equation of the line that passes through (4, 2) and is parallel to the line y = 2x – 1.
Answers
Answer:
Step-by-step explanation:
We will look for a line that has the general form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
A line parallel to y=2x-1 will have the same slope, 2.
We can write y = 2x + b for the new line. We need to find b. We can use the given point in this equation and solve for b:
y = 2x + b
2 = 2(4) + b for (4,2)
2 = 8 + b
x = -6
The parallel line to y=2x-1 that goes through point (4,2) is:
y = 2x-6

We are asked to write the equation of the line that passes through (4, 2) and is parallel to y=2x-1.
[tex]\triangle~\fbox{\bf{KEY:}}[/tex]
Parallel lines have the same slope.Since the slope of the given line is 2, the slope of the line parallel to this one is also 2.
Now, figure out the y-intercept, c:y=2x+c
We're given a point: (4, 2).Where: 2 is the y-coordinate of the point, and 4 is the x-coordinate.
Now, substitute 2 for y and 4 for x:
[tex]\longmapsto\sf{2=2(4)+c}[/tex]
Simplify!
[tex]\longmapsto\sf{2=8+c}[/tex]
Subtract 8 from both sides of the equal sign:

What is the solution to this Equation?
2(5x+8) = 6x+20
A. X = -1
B. X=9
C. X = -9
D. x = 1
Answers
Answer:
D(x=1).
Step-by-step explanation:
2(5x+8)=6x+20
10x+16=6x+20
10-6x+16=6x-6x+20
4x+16=20
4x+16-16=20-16
4x=4
4x/4=4/4
x=1
The solution to this equation is x = 1
Given the equation, we apply the distributive property.
That is, let's multiply the terms:2( 5x + 8 ) = 6x + 20
10x + 16 = 6x + 20
Now we will subtract the terms on both sides of the sentence:10x - 6x = 20 - 16
4x = 4
Finally, let's divide the second to the first term:x = 4 ÷ 4
x = 1
Therefore, the value of this equation is x = 1
Using graphing, what is the approximate solution of this equation? 3xˆ2-6x-4 = -2/x+3 + 1 A. x = .64
B. x = .33
C. x = .18
D. x = 2.60
Answers
Answer: c
Step-by-step explanation:
The required values on the graph, the solution is approximate x = -0.33.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
To solve this equation, we can begin by combining like terms on the left-hand side:
3x² - 6x - 4 - 2/x + 3 + 1 = 0
3x² - 6x - 2/x = -3
Next, we can factor out the x term:
x(3x - 2) - 2(3x - 2) = -3
(x - 2)(3x - 2) = -3
Since the equation is equal to -3, we can add 3 to both sides to get:
(x - 2)(3x - 2) + 3 = 0
We can then factor the left-hand side to get:
(x - 2)(3x - 2 + 3) = 0
(x - 2)(3x - 2 + 3) = (x - 2)(3x + 1) = 0
This equation has two solutions: x = 2 and x = -1/3.
Approximating these values on the graph, we see that the solution is approximate x = -0.33.

Analyzing the quadratic functions, it is found that the correct option is D. The functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.
How to analyze the function?Looking at the graph, Function f has a minimum value of 1 at x = -3. Hence, the axis of symmetry is x = -3.
Function g has a minimum value of 6 at x = -3. Hence, the axis of symmetry is also x = -3.
Therefore, the functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.
