Watch closely:
It's 7x
49
7 + x
7-2x
35
Expressed as an algebraic expression, this would be equal to 7x - 5.
x-7
7 + x
Product means the answer to a multiplication: 8 x 12 = 96 (Not sure what is meant by 'algebraic form' ?)
7-2x
35
It is: 15x
3x
It is two terms of an algebraic expression in the form of: x-15y
Expressed as an algebraic expression, this would be equal to 7x - 5.
x-7
X+-7
175 = 5 x 5 x 7 = 52 x 7
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
