It is: 60+b simplified
It is 2a-b simplified
The value of a + b depends on the values of the individual variables.The expression a + b cannot be simplified.
It is: b -8 when simplified
If you mean: 7b+b+b then it is 9b simplified
2s-2b= a+b+c-2b simplified that would be a+c-b.
It is: b+4 when simplified
There is an ambiguity whether you square the sum of a plus b, or only b. In any case, I don't think you can simplify this expression.
The simplified expression is -9a -9b.
2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
It is simply as stated in the question. Without information about a or b, the expression cannot be simplified nor evaluated.
It's an expression that can't be simplified.
When simplified it is: 2a+8b+4
It is: b+b+b = 3b
b + a + b - a = 2b
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
It is an expression that can be simplified to: 1-4b-5c
a-b+a-b+2b+a = 4a
