Question

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

Answer 1

No, they aren't equal.

Explanation:

4(3x6+6)

4(24)=96

12x6=72

Answer 2

The answer is NO

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.
