Answer:
It is an imaginary number.
Step-by-step explanation:
The square root of negative one is "i," the imaginary number. This concept is immensely useful in mathematics, as it allows for there to be square roots of negative numbers, which is otherwise not possible using only real numbers.
Any number that includes a negative square root is called an imaginary number. For example, the square root of -9 equals 3i, an imaginary number. When an imaginary number and a real number are combined, for example 2 + 3i, this is called a complex number. Complex numbers have many real world applications, including manipulating sound waves and calculating electrical currents.
If the perimeter is fixed and you want to use it to enclose the greatest
possible area, then you form the perimeter that you have into a circle.
If it must be a rectangle, then the greatest possible area you can enclose
with the perimeter that you have is to form it into a square.
Since the perimeter that you have is 18 inches, form it into a square
with sides that are 4.5 inches long.
The area of the square is (4.5)² = 20.25 square inches.
There is no such thing as the 'least possible' area of the rectangle.
The longer and skinnier you make it, the less area it will have, even
if you keep the same perimeter. No matter how small you make the
area, it can always be made even smaller, by making the rectangle
even longer and skinnier. You can make the area as small as you
want it. You just can't make it zero.
Example:
Width = 0.0001 inch
Length = 8.9999 inches
Perimeter = 18 inches
Area = 0.00089999 square inch.
So, the difference between the greatest and least possible area
of the rectangle with the perimeter of 18 inches is
<em> (20.25) - (the smallest positive number you can think of)</em> square inches.
Based on the fact that you are allowed to multiply as many 2's and/ or as many 5's as you want, the last digit of your result can be either a 2, 5 or 0.
<h3>What is the last digit of your result?</h3>
If you multiplied a 5 number with another 5 number, you will either get a 0 as the last digit or a 5 as the last digit:
5 x 5 = 25
5 x 10 = 50
5 x 15 = 75
5 x 25 = 125
If you multiply a 5 with a 2, you result would always end in 0:
5 x 2 = 10
5 x 4 = 20
5 x 6 = 30
If you multiply a 2 with another 2, the result would be a 2:
2 x 2 = 4
2 x 4 = 8
2 x 6 = 12

The perpendicular slope to y = 4x + 1 is y= -1/4x +5
The gcf of -18m and 27 is -9 if not then positive 9, but if you want me to also solve the equation its -18m + 27 is -9(2m - 3) i hope it helps!
