Product means the answer to a multiplication: 8 x 12 = 96 (Not sure what is meant by 'algebraic form' ?)
The best algebraic expression for 7 x plus 12 -4 is 7x+8.
As a algebraic expression it is simply n/8
There is no variable in (8x12)+8, so it would be called an arithmetic expression. It would evaluate to 96+8 = 104.
It is 8*(-4)N which is -32N
Example : 8/a
8(5x) = 40x
n and 8
The nth term is: 4n
It is: 5-8
As an algebraic expression it is: q-8
It is: t+8
It is two terms of an algebraic expression in the form of 6a-8
Let the number be x and so the expression is 8x
x+(-8)This simplifies to x-8
7 + 8 * n
