42÷6=7 42=Perimeter 6=Sides 7=Possible lengths of the hexagon.
First you would isolate (7m) by subtracting 4 from both sides:
4 + 7m - 4 = 5 - 4
This would leave you with:
7m = 1
Then you would isolate m by dividing both sides by 7:
7m/7 = 1/7
Your final answer:
m = 1/7
B:Add
Because when multiplying two numbers written in scientific notation you will have to add the exponents of 10
