Substitute w = 1 and w = 3 to determine if the two expressions are equivalent 4 (3w + 4) 16w + 12

Expressions are not equivalent

Step-by-step explanation:

Given expressions are:

Putting w=1 in both expressions

Both expression have value 28 on w=1

Putting w=3 in both expressions

Both expression have different values at w=3

Hence, in order for the expressions to be equivalent they both should produce same value on w=3 too.

So, it can be concluded that both expressions are not equivalent ..
