Answer:
x=4
Step-by-step explanation:
we know the ratio of left to right is 2:1 because 6:3=2:1
the horizontal lines are parallel, so the other set of numbers follows the same proportions

Find the area of the polygon.
A. 336 feet squared
B. 13,824 feet squared
C. 288 feet squared
D. 384 feet squared
Answer:
12 x 24 = 288
32 - 24 = 8
8 x 12 = 96
96 divided by 2 = 48
288 + 48 = 336 ft2 is your answer.
A function g models a relationship in which the dependent variable doubles for every 3 units the independent variable increases.
Answer:
x-intercept = 3
y-intercept = -2
Step-by-step explanation:
P.S - The exact question is -
Given - A function g models a relationship in which the dependent variable doubles for every 3 units the independent variable increases.
To find - Graph g when g(0) = -2. Identify the y-intercept and x-intercept.
Proof -
By using the given information , we get
g(x) = [tex]\frac{2}{3} x - 2[/tex]
g(0) = 0 - 2 = -2
It also satisfy the condition g(0) = -2
Here,
by comparing with general form of slope-intercept form y = mx + c
where m = slope, c = y-intercept
Slope, m = [tex]\frac{2}{3}[/tex]
For x-intercept,
Put y = 0
⇒[tex]\frac{2}{3} x - 2[/tex] = 0
⇒[tex]\frac{2}{3}x = 2[/tex]
⇒x = 3
So,
x-intercept = 3
For y-intercept,
Put x = 0
⇒y = 0 - 2
⇒y = 2
∴
y-intercept = -2
What is the factored form of the expression x^2 - 16?
Answer:
(x + 4)(x - 4)

x^2 - 16
x^2 + 4x - 4x = 16
x^2 + 4x - 4x - 16
( + 4 ) − 4 ( + 4 )

Heya!
[tex] \underline{ \underline{ \bf{Question}}}: [/tex] In the given figure , ABC is a triangle in which AB = AC. Also a circle passing through B and C intersects the sides AB and AC at the points D and E respectively. Prove that AD = AE.
~Thanks in advance! :)
Answer:
See Below.
Step-by-step explanation:
We are given that ABC is a triangle in which AB = AC.
A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.
And we want to prove that AD = AE.
By the secant-secant theorem (shown below), we know that:
[tex]AD(AB)=AE(AC)[/tex]
We are given that AB = AC. So, by substitution:
[tex]AD(AB)=AE(AB)[/tex]
And by dividing both sides by AB (AB ≠ 0), we acquire:
[tex]AD=AE[/tex]

Solve 16 = 2x − 2. 2 4 6 8
Answer:
The answer to this question is 6.
Step-by-step explanation:
To find the value of x we must find what minus 2 gets us 16. To find this we pretty much just see what 2 to the power gives us 16, therefore we find that 2^4 is 16. We now must solve for x. We take all of our possible solutions and find what minus 2 gets us 4. We then can see that 6-2 is 4 and that 2^4 is 16. Therefore, we can conclude that x is equal to 6.
If the linear equation with a single variable is 2x - 2 = 16. Then the value of the variable x is 9.
What is linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The linear equation with a single variable is given below.
16 = 2x - 2
Then the value of x will be given as
18 = 2x
x = 9
Then the value of the variable x is 9.

A candle burns down at the rate of 0.75 inches per hour. The original height of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

24. Solve the system of equations below: 2x - 6y = - 12 x+2y = 14
how do I do this I don't get it please help
Answer:
(x,y) (28/19, -35/19)
hope this helps
Answer:
x = 6, y = 4
Step-by-step explanation:
multiply the equation x + 2y = 14 by two then subtract the equation 2x - 6y = - 12 to eliminate x and solve for y:
×2 => 2x + 4y = 28
-) 2x - 6y = -12
_________________
10y = 40
=> y = 4
substitute y = 4 to either of the equation 2x - 6y = - 12 OR x + 2y = 14 to solve for x:
=> 2x - 6(4) = -12
=> 2x = 12
=> x = 6

G.130
H.50
Answer:
If you were to make a 360 degree circle and minus the 50 thats already there you get 310 the right angle on angle 5 is 90 degrees because its a right angle so then the 310-90=220 the obtuse angle on angle 2 is 180 so 220-180=40 lastly you share those forty between angles 3 and 4 and the solution is your answer.

11. Find the volume and the surface area of the solid.
Answer:
Part A
The surface area of the solid is 408 cm²
Part B
The volume of the solid is 312 cm³
Step-by-step explanation:
Part A
The surface area of the figure is found by finding the sum of the surface area of the individual rectangles that make up the figure as follows;
The areas of the rectangles are;
A₁ = 6 cm × 2 cm = 12 cm²
A₂ = 6 cm × 4 cm = 24 cm²
A₃ = 6 cm × 6 cm = 36 cm²
A₄ = 12 cm × 6 cm = 72 cm²
A₅ = 2 × 6 cm × 2 cm = 24 cm²
A₆ = 2 × 8 cm × 2 cm = 32 cm²
A₇ = 8 cm × 2 cm = 16 cm²
A₈ = 10 cm × 6 cm = 60 cm²
A₉ = 2 × 12 cm × 2 cm = 48 cm²
A₁₀ = 6 cm × 2 cm = 12 cm²
A₁₁ = 12 cm × 6 cm = 72 cm²
The area, A = A₁ + A₂ + A₃ + A₄ + A₅ + A₆ + A₇ + A₈ + A₉ + A₁₀ + A₁₁
Therefore, A = (12 + 24 + 36 + 72 + 24 + 32 + 16 + 60 + 48 + 12 + 72) cm² = 408 cm²
The surface area of the solid, A = 408 cm²
Part B
The volume is found similarly as follows;
V₁ = 6 cm × 6 cm × 2 cm = 72 cm³
V₂ = 8 cm × 6 cm × 2 cm = 96 cm³
V₃ = 12 cm × 6 cm × 2 cm = 144 cm³
The volume of the solid figure, V = V₁ + V₂ + V₃
∴ V = (72 + 96 + 144) cm³ = 312 cm³
The volume of the solid figure, V = 312 cm³.

420 student 25 times 3 times the number of girls 2 times the number of boys how many girls amd how many boys
Complete Question
We have a total of 420 students. 2 times 3 times the number of girls is equal to 2 times the number of boys how many girls and how many boys
Answer:
The number of boys = x = 315 boys
The number of girls = y = 105 girls
Step-by-step explanation:
Let
The number of boys = x
The number of girls = y
We have 420 students
2 times 3 times the number of girls is equal to 2 times the number of boys
x + y = 420..... Equation 1
2 × 3y = 2x
6y => 2x
x => 6y/2 = 3y
We substitute 3y for x in Equation 1
3y + y = 420
4y = 420
y =>420/4
y => 105
Solving for x
x = 3y
x = 3 × 105
x = 315
Therefore,
The number of boys = x = 315 boys
The number of girls = y = 105 girls

Roger is building a frame for a flower bed. He is using left-over scraps of wood from his garage. He needs a total of 12 feet of wood. The pieces he has in his garage are 314 feet, 412 feet, and 4 feet. Does he have enough wood to build the frame?
A. Yes, because 12 > 1134
B. Yes, because 1234 > 12
C. No, because 1134< 12
D. No, because 1116 < 12
Answer:
C. No, because 11.34 < 12
Step-by-step explanation:
3.14 + 4.12 + 4 has to be greater than or equal to 12
solve the equation
3.14 + 4.12 + 4 >= 12
7.26 + 4 >= 12
11.26 >= 12 is false
I don't know why it says 11.34 because the numbers don't add up, so I'll assume that there is a typo somewhere.
