Answer:
Step-by-step explanation:
Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.
x + 2x + 5 + 6x - 17 + 3x + 2 becomes
12x - 10
The correct answer is 5.60
The answer would be 0.009321 (rounded)
complete would be 0.00932090545 which equals 7/751
If one nickel is 2.1 centimeters, that would mean if you added 2.1 to itself you would get the length of 2 nickels:
2.1 + 2.1 = 4.2 centimeters
