Answer:
10x - 8 or 2( 5x - 4)
Step-by-step explanation:
Perimeter of a rectangle = 2( Length + Width)
<u>Rectangle A </u>
Length = x + 8,
Width = x - 1
![Perimeter_A = 2((x + 8) + ( x - 1))\\\\](https://tex.z-dn.net/?f=Perimeter_A%20%3D%202%28%28x%20%2B%208%29%20%2B%20%28%20x%20-%201%29%29%5C%5C%5C%5C)
![= 2(x + 8 + x - 1) \\\\= 2(2x + 7)\\\\=4x + 14](https://tex.z-dn.net/?f=%3D%202%28x%20%2B%208%20%2B%20x%20-%201%29%20%5C%5C%5C%5C%3D%202%282x%20%2B%207%29%5C%5C%5C%5C%3D4x%20%2B%2014)
<u>Rectangle B</u>
Length = 4x + 5
Width = 3x - 2
![Perimeter _B= 2((4x + 5) + (3x-2))\\\\](https://tex.z-dn.net/?f=Perimeter%20_B%3D%202%28%284x%20%2B%205%29%20%2B%20%283x-2%29%29%5C%5C%5C%5C)
![=2(4x + 5 + 3x - 2)\\\\=2(7x + 3)\\\\=14x + 6](https://tex.z-dn.net/?f=%3D2%284x%20%2B%205%20%2B%203x%20-%202%29%5C%5C%5C%5C%3D2%287x%20%2B%203%29%5C%5C%5C%5C%3D14x%20%2B%206)

Hi friend
3868000000 in scientific notation is : 3.868* 10^9
I hope that's help:) Please rate
If you have any further questions please let me know.Thx
Answer:
0.6763154335
Step-by-step explanation:
because. 10%is the same as 10 over 100 .because percent means 100. so you say 100÷10=10. then you say 10×14.786. this is how I got the answer.
The y-intercept is changed from 2 to -4.
That means that the point that the graph crosses the y axis has been moved down by 6.
Since the slope of the line has not changed, this just means the graph of the line will be moved down by 6.
Hope this helps!

Option A : a+o = 92 , 4a+2o = 284 is the right answer
Step-by-step explanation:
Let o be the number of oranges sold on Friday and
a be the number of apples sold on Friday
So,
A total of 92 was sold on Friday will yield the equation
![a+o = 92](https://tex.z-dn.net/?f=a%2Bo%20%3D%2092)
On Saturday,
4 times the number of apples = 4a
2 times the number of oranges = 2o
So,
![4a+2o = 284](https://tex.z-dn.net/?f=4a%2B2o%20%3D%20284)
Hence,
The system of equations is:
![a+o = 92\\4a+2o = 284](https://tex.z-dn.net/?f=a%2Bo%20%3D%2092%5C%5C4a%2B2o%20%3D%20284)
Option A : a+o = 92 , 4a+2o = 284 is the right answer
