On simplifying the expression 13.8+ (-11.5) , we get 2.3 . And additions
13.8 + (-11.5) and (-13.8) + 11.5 are numbers will same value and opposite sign.
<h3>What are rules for adding a positive and a negative number?</h3>
For adding a negative and a positive number, use the sign of the larger number and subtract.
For example: (–8) + 2 = -6
Given that we have to solve 13.8 + (-11.5) = 13.8-11.5 (we subtract smaller no from larger and will use the sign of lager number that is + here)
13.8+(-11.5) = 13.8-11.5 =2.3
13.8+(-11.5) simply means that 13.8 -11.5 which is subtraction of 11.5 from 13.8
but (-13.8) + 11.5 = -13.8 +11.5 = -( 13.8 -11.5) [taking -1 common from the expression]
Therefore , -13.8 + 11.5 has same value as 13.8- 11.5 but opposite in sign.

Answer:

Step-by-step explanation:
√2=1.41
So, the smallest possible interval will be 1.40 and 1.42
√3=1.73
So, the smallest possible interval will be 1.72 and 1.74
√4=2.00
So, the smallest possible interval will be 1.99 and 2.01
√5=2.24
So, the smallest possible interval will be 2.23 and 2.25
√6=2.45
So, the smallest possible interval will be 2.44 and 2.46
Answer:
The reflection is in the y-axis cause the y point went from -7 to 7 and the x point stayed the same.
Answer:
