Answer:
-1.875
Step-by-step explanation:
1. Write the problem: -2(5x + 8) = 14 + 6x
2. Multiply -2 by 5 and 8 to get: -10x - 16 = 14 + 6x
3. Combine like terms: -16x - 16 = 14
4. Repeat step 3: -16x = 30
5. Divide -16 by 30 to get the answer which is -1.875.
Hope this helped!
Answer:
Note :
The perimeter is : AB + BC + CA
AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180
AB = √(36×5) = 6√5 units
same method for : BC ; CA ..........

Answer:

Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.
The nth term is given by the following equation:

In which
is the first term and d is the common difference.
First term is 9 common difference is -2
This means that 
So, the nth term is given by:
