0.25 is the answer. If you want it in fraction form it would be 25/100 which can be simplified down to 1/4

Answer:
8m³ -4m² +3m
Step-by-step explanation:
The perimeter of a triangle is the sum of the lengths of its three sides. Here, you're given the perimeter and two of the sides. The third side will be the length that makes up the difference.
P = side 1 + side 2 + side 3
18m³ +2m² -m = (5m³ +3m² -2m) +(5m³ +3m² -2m) + side 3
18m³ +2m² -m = (10m³ +6m² -4m) + side 3 . . . . . collect terms
18m³ +2m² -m - (10m³ +6m² -4m) = side 3 . . . . . subtract (10m³ +6m² -4m)
m³(18 -10) +m²(2 -6) +m(-1 +4) = side 3 . . . . . . . . . group like terms
8m³ -4m² +3m = side 3
If there are 4 marbles left over each time, then we can forget about them for now.
So the question is, what is the smallest number than can be divided into 6,7 and 8?
the numbers have only one non-1 divisor in common: both 6 and 8 are divisible by 3.
so for our purposes we can "delete" one 2 and ask:
what is the smallest number than can be divided into 3,7 and 8 ?
There are no more divisors in common, so we just have to multiply them: 3*7*8=21*8=168
and the 4 marbles "extra"? We add them to this sum.
the the smallest possible number in the box is 168+4=172.
To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form.
