4m
first, multiply the base and height then divide it into 2 example: base:4m height:2m multiply 4 by 2= 8 then divide 8 by 2= 4 4m squared
3m 45.56s is 14.44s from 4m 4m is 2m 28.5s from 6m 28.5s 0m 14.44s + 2m 28.5s = 2m 42.94s or 388.5 - 225.56 = 162.94 = 2m 42.94s Q.E.D.
6m + 5n - 4m + 7n = 2m + 12n
2m + 13n
It is: 2m times 2m is equivalent to 4m^2
4m
74
There is none because to form a triangle the sum of its two smaller sides must be greater than its longest side
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
40m^3
first, multiply the base and height then divide it into 2 example: base:4m height:2m multiply 4 by 2= 8 then divide 8 by 2= 4 4m squared

6m + 5n - 4m + 7n = 2m + 12n
None. By definition a hole is an empty space.
