Step-by-step explanation:
m - 6 = - 3
send - 6 to the other side
m = - 3 + 6
when you send something to the other side it gets the opposite sign. If it was a minus sign it will be plus sign or if it was a minus sign it will be a plus sign. So - 6 became +6 when we send it to right side of the equation.
Now we need to sum - 3 +6
m = - 3 +6
m = + 3
You may not need the plus sign and you can directly write m = 3

The answer is length AD is 3cm
Answer:
solve the equation with known values filled in; width is 3 ft.
Step-by-step explanation:
The perimeter formula can be used to find a missing value by filling in all of the known values, and solving the resulting equation.
__
P = 2(L +W) . . . . . . perimeter formula
14 = 2(4 +W) . . . . . known values substituted
7 = 4 +W . . . . . . . divide by 2
3 = W . . . . . . . . . subtract 4
The width is found to be 3 feet using the perimeter formula.
