The side lengths of A'A and B'B are 18 and 9 respectively.

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.

Step-by-step explanation:

There's a total of 15 squares.

So the percentage that is gray would be [tex]\frac{6-gray-squares}{15-total-squares}[/tex] which simplifies to [tex]\frac{2}{5}[/tex] in fraction form or 40%

Answer:

X= .5 (decimal form)

X= 1/2 (Exact form)

Answer: 5

Work Shown:

f(x) = 2x+1

f(2) = 2*2+1 ... x has been replaced with 2

f(2) = 4+1

f(2) = 5

The input is x = 2. The output is y = 5.

Answer:

13

Step-by-step explanation:

It is a parallelogram so the opposite angles are the same.

All angles sum to 360 degrees.

This means that the adjacent angles sum to 180 degrees.

4a + 11 + 9a = 180 = 13a + 11

13a = 169

a=13

First, apply the distributive property:

-30 = 5(x + 1)

-30 = 5x + 5

Substract 5 from both sides:

-30 - 5 = 5x + 5 - 5

-35 = 5x

Divide both sides by 5:

[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]

[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]

‎      

Let's check the answer:

-30 = 5(x + 1)

-30 = 5(-7 + 1)

-30 = 5(-6)

-30 = -30

The answer is correct.

Answer:

10 yards

Step-by-step explanation:

;)

The required length of the longer side is 10 yards.

Perimeter, is the measure of the figure on its circumference.

Here,
Let's assume that the length of one side of the rectangle is x yards. According to the problem, the other side of the rectangle is 3 yards longer than twice the length of this side. So, the length of the other side can be expressed as 2x + 3 yards.

The perimeter of a rectangle is the sum of the lengths of all its sides. So, we can write an equation to represent the problem:

Perimeter = 2 × length + 2 × width

Substituting the expressions for length and width, we get:

27 = 2(x) + 2(2x + 3)

27 = 2x + 4x + 6

27 = 6x + 6

21 = 6x

x = 3.5

So, the length of one side of the rectangle is 3.5 yards. The other side of the rectangle is 2(3.5) + 3 = 10 yards.

Therefore, the length of the longer side is 10 yards.
