Expression
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
Given to us
0.6(-7 - 1.2x)
The value of the expression
Therefore any expression equal to this will be the equivalent expression
A.) -4.2 - 1.2x
As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.
B.) -4.2 - 0.72x
This expression will be equal to the desired expression. Thus, this is an equivalent expression.
C.) -0.72x + (-4.2)
On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.
D.) -4.2 + 0.72x
As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.
E.) -4(0.18x + 1.05)
On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.
F.) 0.6(-7) - 0.6(-1.2x)
As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.
G.) 0.6(-7) + 0.6(-1.2x)
On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.

Answer:
-4.2 - 0.72x (second)
-0.72x + (-4.2) (third)
-4(0.18x + 1.05) (fifth)
0.6(-7) + 0.6(-1.2x) (seventh)
Step-by-step explanation:
okay so 0.6(-7 - 1.2x) = -4.2 - 0.72x or -0.72x - 4.2 or -4.2 + (-0.72x) or -0.72x + (-4.2) they are all the same meaning these are all the simplified answers
so the first one is incorrect because it is -4.2 - 1.2x (simplified)
the second one is correct because it is -4.2 - 0.72x (simplified)
the third one is correct because it is -0.72x - 4.2 (simplified)
the fourth one is incorrect because it is -4.2 + 0.72x (simplified)
the fifth one is correct because it is -0.72x - 4.2 (simplified)
the sixth one is incorrect because it is -4.2 + 0.72x (simplified)
the seventh one is correct because it is -4.2 - 0.72x (simplified)
