Answer
The statement that does not represent an expression are 4 + x = 12 and x^2 = 24 which are option B and C respectively
Step-by-step explanation:
An expression is a set of term combined using the operators +, - /
From the option given
8+ x - 7 this can be further expressed as
8 + x - 7
x + 8 - 7
x - 1
The only expression in the option are x - 1, and 5
4 + X = 12 is an equation. This is because it is a combination of two expressions that are equal to each other
x^2 = 24 is also an equation
Therefore, the statement that does not represent an expression are 4 + x = 12 and x^2 = 24 which are option B and C respectively
