The side lengths of A'A and B'B are 18 and 9 respectively.
What are similar triangles?When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.
Given that, segment A'B' is parallel to segment AB.
Let A'A =x and B'B = y.
Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.
As per the property of similar triangles, it follows:
12/8 = (12 + x)/20
12 + x = (12/8)20
x = 18
And,
6/8 = (6+y)/20
6 + y = (6/8)20
y = 9
Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

3х + Зу = -x+5y ordered pair
Answer:
2x-y=0
x=1/2y
Step-by-step explanation:
Answer:
Your solution is (1/2, 1).
Step-by-step explanation:
3х + Зу = -x + 5y
First we want to look at each side of the equation separately.
3х + Зу ⇒ This expression is fully simplified because you cannot add different variables together.
-x + 5y ⇒ This expression is fully simplified because you cannot add different variables together.
3х + Зу = -x + 5y
Now, let's bring the like terms together.
[add x to both sides]
x + 3x + 3y = -x + x + 5y
4x + 3y = 5y
[subtract 3y from both sides]
4x + 3y - 3y = 5y - 3y
4x = 2y
We want to solve for one variable at a time, so let's isolate x.
[divide both sides by 4]
4x/4 = 2y/4
x = 1/2y
Now we have an expression for x. Plug this expression in to your original equation.
3х + Зу = -x + 5y
3(1/2y) + 3y = -(1/2y) + 5y
According to PEMDAS (parentheses/exponents | multiplication/division | addition/subtraction), we should multiply first.
3(1/2y) + 3y = -(1/2y) + 5y
3/2y + 3y = -1/2y + 5y
Now let's add on each side.
9/2y = 9/2
Now we need to isolate y by dividing both sides by 9/2 (or multiplying by its reciprocal 2/9 ← This is often easier to understand when written)
[tex]\frac{2}{9} (\frac{9}{2} y) = \frac{9}{2} (\frac{2}{9} )[/tex]
In this form, we can see that the fractions cancel each other out.
y = 1
Now that we have the value of y, plug it into our equation for x.
x = 1/2y
x = 1/2(1)
Multiply.
x = 1/2
Your solution is (1/2, 1).
You're almost done! Check your answer by plugging in both these values in to your original equation.
3х + Зу = -x + 5y
3(1/2) + 3(1) = -(1/2) + 5(1)
Multiply.
3(1/2) + 3(1) = -(1/2) + 5(1)
3/2 + 3 = -1/2 + 5
Add.
9/2 = 9/2
This equation is true, therefore your answer is correct!

Find the volume of this object.
Use 3 for 1.
Volume of a Cylinder
V= Tir2h
Volume of a Cone
15cm
V= 7r2h
3
14cm
V
V~ [?]cm3
Answer:
171 cm³
Step-by-step explanation:
The object is composed of a cone and a cylinder.
Volume of the object = volume of cone + volume of cylinder
✔️Volume of Cone = ⅓πr²h
r = ½ of 6 = 3 cm
π = 3
h = 5 cm
Volume of cone = ⅓×3×3²×5
Volume of cone = 45 cm³
✔️Volume of cylinder = πr²h
π = 3
r = ½ of 6 = 3 cm
h = 14 cm
Volume of cylinder = 3×3×14
Volume of cylinder = 126 cm³
✔️Volume of the object = 45 + 126 = 171 cm³

Step-by-step explanation:
So, for a triangle, if you add any two sides, it will always be greater than the third side.
So if a triangle has sides of 1, 1, and 1:
1 + 1 > 1
1 + 1 > 1
1 + 1 > 1
So this is a triangle.
For a triangle with the sides of 3, 3, and 9:
3 + 9 > 3
9 + 3 > 3
3 + 3 > 9 (this one is not true)
So, these can't be the values of the sides of a triangle.
For your situation, you have a triangle with sides of 4, 6, and x.
We need to find out what x is, so:
4 + 6 > x
4 + x > 6
6 + x > 4
Isolate x to one side and simplify all the inequalities. You will get:
x < 10
x > 2
x > -2
So, -2 < x < 10.
If you plug in your answer choices, it will be 9.

You have $1,000 of birthday money in a savings account that earns 8% simple interest. If you have not spent any of it for 5 years, what is your TOTAL balance? (Balance = Principal + Interest)
Answer:
Your Balance Would Be $1400.
How I Found The Answer:
$1000 Is 100%
$1000 ÷ 100 = $10
$10 Is 1%
$10 × 8 = $80
$80 × 5 = $400
$1000 + $400 = $1400
Your Balance Would Be $1400.
