Which best proves why the expressions 4(x+3)+2x and 6(x+2) must be equivalent expressions?
when x 3, both expressions have a value of 30.
when - 5. both expressions have a value of 42
when x 1. both expressions have a value of 18, and when x 8, both expressions have a value of 60.
when - 2. both expressions have a value of 15, and when x-6, both expressions have a value of 39.

When , both expressions have a value of 30.

When . both expressions have a value of 18, and when , both expressions have a value of 60.

Step-by-step explanation:

Given:

Solving the equation further we get:

Now, When , both expressions have a value of 30.

Substituting Value of x in equation 1 we get,

Hence the above Statement proves as Correct with given values.

Now, When , both expressions have a value of 42.

Substituting Value of x in equation 1 we get,

Hence the above Statement does not proves as Correct with given values.

Now,When, both expressions have a value of 18, and when , both expressions have a value of 60.

Substituting Value of x in equation 1 we get,

Hence the above Statement proves as Correct with given values.

When . both expressions have a value of 15, and when , both expressions have a value of 39.

Substituting Value of x in equation 1 we get,

Hence the above Statement does not proves as Correct with given values.
