Answer:
6
Step-by-step explanation:
To add expressions where many different variables are used, be sure to remember like terms. Like terms are terms which have the same variable bases and exponents. For instance a and b are different bases but ab and ab are the same. a^2b and ab^2 are different bases while a^2b^2 and a^2b^2 are the same. Both the variable and the exponents must be the same.
In this expression, there is 1 variable with the same exponent. x should be combined with x and constants with constants.
(x/2-7x+6)+(x/2+6x)
- x/2 + x/2 - 7x + 6x = x - 7x + 6x = 0x
- 6
The simplified expression is 0x + 6 which is just 7=6.

Perimeter is distance around the outside white area is the space inside the shape
The correct answer is 26.6 repeating.
You do 400/15
Decimal: 25.3333, but converted properly it is
.253333....(repeating) so to the nearest thousands it would be .253
