Question

Are the two expressions equivalent when x=6. 4(3x+x) and 12x

Answer 1

Answer:

No, they aren't equal.

Step-by-step explanation:

4(3x6+6)  

4(24)=96

12x6=72

Answer 2

Answer:

The answer is NO

Step-by-step explanation:

The condition for two expressions are equivalent is that when you replace the variable by a number and both expressions result are equal.

We have two expressions:

$4(3x+x)\\4(4x)\\16x$

and

$12x$

Given x=6, we replace this number in both equations:

$16x\\16*(6)\\96\\\\12x\\12*(6)\\72$

Therefore, both results are not the same, that it means, the expressions are not equivalent.
