expressions to match it.
a 2(x+4)
6. 8+2x
c. 2x+4
d. 3(x+4)+(4 + x)
ex+4
Answer:
a and b are equivalent.
c, d and e are not equivalent.
So, 2 equivalent expression for c and are,
c.
( i ) 2 ( x + 2 )
( ii ) ( 4x + 8 ) / 2
d.
( i ) 3x + 16
( ii ) ( 6x + 32 ) / 2
Step-by-step explanation:
a.
2 ( x + 4 )
= 2 ( x ) + 2 ( 4 )
= 2x + 8
b.
8 + 2x can also be written as 2x + 8.
d.
3 ( x + 4 ) + ( 4 + x )
= 3 ( x ) + 3 ( 4 ) + 4 + x
= 3x + 12 + 4
= 3x + 16

Step-by-step explanation:
38.42 + 7 is 45.42, and 45.42 + 0.1 is 45.52
Answer:
Let's look at the whole numbers first and put aside the decimals;
38 and 7, let's add these two: 38 + 7 = 45
Now let's look at the decimals;
0.42 and 0.10, let's add these two:
0 . 4 2 0 . 1 0+ _______
0. 52 → Next, we add the decimals and the whole numbers:45 + 0.52
= 45.52, 45.52 is your answer.At a gymnastics meet, three judges evaluate the balance beam performances of five gymnasts, using a scale from 1 to 10, where 10 is a perfect score. A statistician wants to see if the gymnasts (Factor A) differ in their performances and also wants to see if the scores vary significantly across judges (Factor B) in order to assess any bias in the judges. To do this the statistician uses a two-way ANOVA without interaction and the results are show below. At 0.05 level of significance, what is the critical value for testing differences in mean scores across the Gymnasts
Answer:
As 2.551 < 3.84 therefore we reject H0.
As 44.803 > 4.46 so we accept null hypothesis.
Step-by-step explanation:
The answer is attached.
There are three judges so v1 = 3-1= 2 and v2 = (4*2)= 8
There are five gymnasts so v1 = 5-1= 4 and v2= (4*2)= 8
For alpha = 0.05 we find the value of F1 and F2 from the table.

the area of rectangular garden is 27000m2.if the ratio of length and beradth is 10:3 findits perimeter
Given :
The area of rectangular garden is 27000m² .The ratio of length and breadth is 10 : 3 .⠀
To Find :
The perimeter of the rectangular garden.⠀
Solution :
Let us assume the length as 10x m and breadth as 3x m .
⠀
We know that,
[tex]{ \longrightarrow{\quad \sf \pmb{ Length \times Breadth = Area_{(rectangle)}}} }[/tex]
⠀
Now, substituting the values in the formula :
[tex]{ \longrightarrow{\quad \sf{ 10x \times 3x = 27000 }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ 30 {x}^{2} = 27000 }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ {x}^{2} = \dfrac{27000}{30} }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ {x}^{2} = 900 }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ {x}= \sqrt{900} }}} [/tex]
[tex]{ \longrightarrow{\quad \bf{ {x}= 30 }}} [/tex]
⠀
Therefore,
Length = 10x m = 10(30) m = 300 mBreadth = 3x m = 3(30) m = 90 m⠀
Now,
We know that,
[tex]{ \longrightarrow{\quad \sf \pmb{Perimeter_{(rectangle)}=2(Length + Breadth) }} }[/tex]
⠀
Substituting the values in the formula :
[tex]{ \longrightarrow{\quad \sf {Perimeter_{(rectangle)}=2(300 + 90) }} }[/tex]
[tex]{ \longrightarrow{\quad \sf {Perimeter_{(rectangle)}=2(390) }} }[/tex]
[tex]{ \longrightarrow{\quad \bf \pmb {Perimeter_{(rectangle)}=780 }} }[/tex]
⠀
Therefore,
The perimeter of the rectangular garden is 780 m .The perimeter of the rectangle whose area is 27000 m² is 780 m.
What is the perimeter of a rectangle?The perimeter of a rectangle is the determinating of all the sides of the rectangle. In the given question, we have the following parameters:
Given that:
The area of the rectangle = 27000 m²The ratio of the length and the breadth is 10: 3It implies that, if the length is 10x, the breadth is 3x
The area of a rectangle = length × breath
27000 m² = (10x) × (3x)
27000 m² = 30x²
x² = 27000/30
x² = 900
x = √900
x = 30
Now, we can say that:
The length = 10(30) = 300The breath = 3(30) = 90The perimeter of the rectangle = 2(length + breadth)
The perimeter of the rectangle = 2(300 + 90)
The perimeter of the rectangle = 780 m

16.3x42.7+22.5x16.3 = 1062.76 (approximately 1063)
Answer:
1063 cm^2
Step-by-step explanation:
notice you have 4 triangles. Take advantage of that!
the formula for a triangle:
[tex]\frac{base * height}{2}[/tex]
the triangles on the left side are the same so
2 * ([tex]\frac{42.7 * 16.3}{2}[/tex]) = 696.01 cm^2
I multiplied it by 2 because there are two corresponding triangles.
on the right side it's the same:
2 * [tex]\frac{22.5 * 16.3}{2}[/tex] = 366.75 cm^2
Now add those values: 696.01 + 366.75 = 1,062.76 cm^2
make sure you round to the nearest square centimetre: then the answer is 1063 cm^2.
You could also use the area of a rhombus.

if y²-x=7, find the positive value of when x=9.
Answer:
y = + 4
Step-by-step explanation:
y² - x = 7 ← substitute x = 9 into the equation
y² - 9 = 7 ( add 9 to both sides )
y² = 16 ( take square root of both sides )
y = ± [tex]\sqrt{16}[/tex] = ± 4
the positive value of y when x = 9 is + 4
Answer:
4
Step-by-step explanation:
when x = 9:
⇒ y² - 9 = 7
⇒ y² = 7 + 9
⇒ y² = 16
⇒ y = √16
⇒ y = ±4
Therefore, the positive value of y = 4

The formula for finding perimeter is add all sides.[tex]23 + 6 = 29[/tex] « First two lengths
[tex]8 + 9 = 17[/tex] « Second lengths
[tex]23 - 9 = 14missing[/tex] « The missing length which was difficult for me
[tex]17 + 29 + 14 + 2 = 62[/tex] « Adding all lengths combined
Hope this helps. Let me know if it's right this time.
Answer:
62
Step-by-step explanation:
Ok so we have all but two identified lengths, but we can find them pretty quickly. To find the horizontal unidentified length, we can write 23-9=14 and get out length. To find the vertical length we can write 8-6=2 to get the length. Now add all lengths together 23+8+9+2+14+6=62 to get the perimeter. Just putting it here for the points :)

Find the value of\xx, y.y, and zz in the parallelogram below.
Answer:
Step-by-step explanation:
The value of x, y, and z in the parallelogram are, - 40, - 60 and 1 respectively.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram.
The opposing or confronting sides are of equal length and the sum of the adjacent angles is of equal measure.
From the given diagram,
(- 3x - 3)° + 63° = 180°.
- 3x - 3° + 63° = 180°.
x = - 40.
Similarly,
(- 3x - 3)° + (- y + 3°) = 180°.
-3(-40) - 3° - y + 3° = 180°.
y = - 60.
And,
(- y + 3°) + (z - 4°) = 180°.
180° + 3° + z - 4° = 180°.
z = 1.
