I think the best way in memorizing the roots of numbers 1 - 30 is by through methods that would suitable for you but you must consider is the pattern in each number or the square, every number has it pattern and i know you realized it by now. I hope this would help

Answer: D) 144 square cm</h3>
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.
---------
Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
<span>No because a negative times a negative will be positive and it will not equal a negative number. the square root cannot be one negative and one positive because that is against the definition of a square root.

Y = 350x + 6500
where x = the number of months you own the car and y = the total cost of buying and owning the car.
This is true because each month, it costs 350, so finding the monthly cost would be multiplying 350 by the number of months, or x. The + 6500 is there because in addition to the monthly cost, the original price was $6500.
