As we are looking for the perimeter of the polygon, we should understand the formula for each figure. For #2, we can clearly see that we have a square, which concludes that the perimeter for the figure is going to be 4S ('S' being the length of one side as all sides are equal).
Let's apply this to our problem.
P = 4S;
S = 6x + 3; set this up as an equation.
P = 4(6x + 3); apply the distributive property to the right side of the equation.
P = 4(6x) + 4(3);
P = 24x + 12
As we can see above, the perimeter of the square in problem #2 is going to be 24x + 12.

-x+y=5 4x+y=10 Use addition to solve the linear system of equations. Include all of your work in your final answer
Answers
x = 1
y = 6
Explanation:
The first given equation is:
-x + y = 5
Multiply this equation by -1, you will get:
x - y = -5 ............> I
The second given equation is:
4x + y = 10 ..........> II
Add the two equations I and II as follows:
x - y = -5
+ 4x + y = 10
..............................
5x = 5
Therefore:
x = 5/5
x = 1
Substitute with x in equation I to get y as follows:
x - y = -5
1 - y = -5
y = 1 + 5
y = 6

Adelaide paid $35 for a manicure and gave the manicurist a 20% tip How much money did Adelaide give her manicurist
Answers
$42.
Explanation:
The best way to find a total bill including tip (or tax if that is what you are looking for - it is found the same way), is to multiply the original total by 1 + the percentage of the tip.
Since the percentage is 20%, we add 0.20 to 1 to get 1.20.
Now we multiply that by the original cost to get the final answer.
1.20*35 = 42
Answer:
Adelaide gave $ 42 to the manicurist.
Step-by-step explanation:
Here, the original price of the manicure = $ 35
Since, 20% tip is given to manicurist,
Thus, the total payment for manicure = Original price of the manicure + 20 % of the original price of the manicure
= 35 + 20 % of 35
[tex]=35+\frac{20\times 35}{100}[/tex]
[tex]=35+\frac{700}{100}[/tex]
[tex]=35+7[/tex]
[tex]=42[/tex]
Hence, Adelaide gave $ 42 to the manicurist.

6x + 2x + 2x = 180 Then combine all the x's and simplify by dividing.
Answer:
36 °
Step-by-step explanation:
Hello
In geometry an interior angle or an internal angle is an angle formed by two sides of a polygon that sharing a common end is contained within the polygon, and the sum of these angles is given by
sum=(n-2)*180°
where n is the number of sides of the polygon,in our case n= 3 (a triangle)
Step 1
find the sum o internal angles
sum=(3-2)*108°
sum=1*180°
(1)sum=180°
step 2
find x
now, according to the graph the sum of internal angles is
sum(graph)=6x+2x+2x
(2)sum=10x
(1) must be equal to (2)
180°=10x
isolating x
x=18
Step 3
find C
by the graph ,we know
C=2x
and x=18
replacing
C=2(18)
C=36°

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that volume of a right rectangular shipping carton is 948.75 cubic meters.
The height of the shipping carton is 11 meters, and the width is 7.5 meters.
We have to find the length of the shipping carton
V=Length × width × height
V= Length x 7.5 x 11
948.75 = 82.5 length
Divide both sides by 82.5
Length = 948.75/82.5
Length = 11.5 meters
Hence, if volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.

find an inequality that you can use to disprove John statement. explain your thinking.
Answers
-x > 0
According to John, we multiply both sides by -1, and the inequality sign does not change direction, so we get this
x > 0
Let's use a number for x that makes the original inequality true.
Let x = -2.
-x > 0
-(-2) > 0
2 > 0
As you can see, -2 does work on the original equation.
Now let's try -2 in John's solution.
x > 0
-2 > 0 which is a false statement.
Now let's solve it again, but we will reverse the inequality symbol when we multiply both sides by -1.
-x > 0
x < 0
Try x = -2.
-2 < 0 which is true
Now it works.
John is incorrect.
If you multiply or divide an equation by a negative number, even if one of its sides is 0, you still must change the direction of the inequality symbol.

In the coordinate plane, what is the length of the line segment that connects points at (4, −1) and (9, 7) ? Enter your answer in the box. Round to the nearest hundredth.
Answers
d=√(x2-x1)^2+(y2-y1)2^2
d=√(9-4)^2+(7--1)^2
d=√(5)^2+(8)^2
d=√(25)+(64)
d=√89
d=9.43 units
The length of the line segment is 9.43 units.
Final answer:
The length of the line segment connecting points (4, -1) and (9, 7) in the coordinate plane is approximately 9.43 units, when rounded to the nearest hundredth.
Explanation:
To find the length of the line segment that connects the points (4, −1) and (9, 7) in the coordinate plane, we can use the distance formula which is derived from the Pythagorean theorem:
The distance (Δ) between two points (x1, y1) and (x2, y2) is given by:
Δ = √((x2 - x1)² + (y2 - y1)²)
Substituting the given coordinates:
Δ = √((9 - 4)² + (7 - (−1))²)
Δ = √(5² + 8²)
Δ = √(25 + 64)
Δ = √89
Using a calculator, we can find that:
Δ ≈ 9.43
Therefore, the length of the line segment is approximately 9.43 units, rounded to the nearest hundredth.

a 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building. what angle does the ladder make with the ground?
Answers

The ladder makes an angle of 63.43 degrees with the ground.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building
We need to find the angle which the ladder make with the ground.
tan(x) = opposite side / adjacent side
In this case, the opposite side is the height of the building, which is 20 feet.
The adjacent side is the distance from the wall to the base of the ladder, which is 8 feet.
Plugging in the values:
tan(x) = 20 / 8
x=tan⁻¹(20/8)
x=63.43 degrees
x is the angle
Hence, the ladder makes an angle of 63.43 degrees with the ground.

A) 1.4 cm

C) 6.0 cm
D) 7.3 cm
Answers
B) 4.0 cm
ExplanationFirst, we can adapt the law of sines to the notation of our triangle:
[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]
Now, we can infer from our diagram that [tex]W=39[/tex], [tex]U=31[/tex], and [tex]u=3.3[/tex], so we can replace the values in our previous expression:
[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]
[tex]\frac{sin(39)}{w} =\frac{sin(31)}{3.3}[/tex]
Finally, we can solve for [tex]w[/tex]:
[tex]\frac{3.3sin(39)}{w} =sin(31)[/tex]
[tex]3.3sin(39)=wsin(31)[/tex]
[tex]\frac{3.3sin(39)}{sin(31)} =w[/tex]
[tex]w=\frac{3.3sin(39)}{sin(31)}[/tex]
[tex]w=4.03224[/tex]
Which rounds to [tex]w=4.0[/tex]
