Step-by-step explanation:
Expanded notation may be defined as the way of expressing a number by exhibiting its value of each of the digit.
In an expanded notation, the number is always represented as a summation of each of the digit times its place value, while in the expanded form, an addition is used between the place value numbers.
A number containing zero can be written in the expanded form as for example,
509,300
Since digit 5 is 100,000th place, 9 is in 1,000th place and the digit 3 is 100th place, the number can be written as --
5 x 100,000 + 9 x 1,000 + 3 x 100
SIMILARITIES
Some similarities are that for linear and non-linear systems of equations, you need the same number of equations as unknowns to solve the system and find the only solution for each variable.
DIFFERENCES
Some differences are
The linear system of equations has degree "1" in each of its variables.
The non-linear system of equations has degree "n" in each of its variables.
where n = 1,2,3, ..., i, ..., n.
<u>Answer:</u>
Minimum possible area = 6.75 km^2
Maximum possible area = 13.75 km^2
<u>Step-by-step explanation:</u>
This question relates to significant figures so assuming that each of the given values is rounded off to the nearest kilometer.
So we can find the minimum and maximum possible areas of the rectangle.
Minimum possible area of rectangle = 1.5 × 4.5 = 6.75 square kilometers
Maximum possible area of rectangle = 2.5 × 5.5 = 13.75 square kilometers
