5x - 2x + 8 = 2 + 6x + 6
Add like terms:
5x - 2x = 3x
2 + 6 = 8
3x + 8 = 6x + 8
To isolate the variable, subtract 6x from both sides of the equation:
3x - 6x = -3x
-3x + 8 = 8
Now subtract 8 from both sides:
8 - 8 = 0
-3x = 0
To finish, divide both sides by -3:
0 ÷ -3x = 0
The answer is x = 0
Hope this helps.
A=45 degree I had the same example ... Even if a angle is 90 degrees is not necessarily a right triangle, so the angle A = 45 degrees
For this case we have that by definition the area of a rectangle is given by:

Where
- <em>w: width of the rectangle
</em>
- <em>l: length of the rectangle
</em>
The area of the original rectangle is given by:

The area of the new rectangle is given by:

Therefore, the original area increases with a factor of 9.
Anwer:
the original area increases by a factor of 9.
