The expression Β 2(m β 4) + 1 is equivalent to 2m - 7 .
Step-by-step explanation:
As the expression given in the question is as follows
= Β 2(m β 4) + 1
Now first open the bracket of the above experession
= 2m - 8 + 1
Simplify the above
= 2m - 7
Therefore the expression Β 2(m β 4) + 1 is equivalent to 2m - 7 .
