Answer:
18 < x + (-3)
Step-by-step explanation:
If the chalkboard is just rectangular we can just use:
(2 x L) + (2 x W)
or
L+L+W+W
L= Length
W= Width
The difference between the given values as a whole number is 27
<h3>Finding the difference between values</h3>
To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value.
Given the following expression
44 - 17
This can also be expressed as
44 = 40 + 4
17 = 10 + 7
Substitute
44 - 17 = (40 + 4) - (10+ 7)
Expand
44 - 17 = 40 + 4 -10 - 7
44 - 17 = 40 - 10 + 4 - 7
44 - 17 = 30 - 3
44 - 17 = 27
Hence the difference between the given values as a whole number is 27
