Respuesta :
Given expression are equivalent.
Yes, When m = 4, the value of expression A is 28 and the value of expression B is 28.
What are Equivalent expression ?
Equivalent expression are those which gives equal answer while putting any value in the given expression.
For example:
1. x + x + x + x and 4x are equivalent expression.
when we put x = 1 both equation become equal to 4.
Here, we have given two expression :
Expression A: 2 ( m + m + m) + m
Expression B: (3+4)m
Now, we can clearly see:
Expression A simplifies to 2(3m) + m = 7m
Expression B simplifies to 7m
Now when we put m = 4
Expression A becomes: 7m = 7 x 4 = 28
Expression B becomes 7m = 7 x 4 = 28
we can clearly see that both the values are equal.
Hence,
Given expression are equivalent.
Yes, When m = 4, the value of expression A is 28 and the value of expression B is 28.
