2a+b=2a+b. Without a value for a and b, the expression has no value.
Unless you have a value for 'h', the answer will just be an expression: 10 + 7h
Negative 12 minus 3 plus 9 is equal to -6
++ is an operator that increments the operand. The value of the operand in the expression is incremented first if the ++ is before the operand. The value of the operand in the expression is the same value if the ++ is after the operand.
The value expression of 60 minus 20 plus 70 is equal to 110.
It is 25.
It is a quadratic expression which when factored is (2y+3)(y+5)
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
