The rounded form of 347500 for given cases gives 348000, 350000 and 300000.
Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
For this case, we've got the number 347,500
Rounding it for given cases:
Rounding to nearest thousand means rounding to the digit whose value is in thousands (from 0 to 9).
This is the fourth digit from right of the decimal.
347500 = 347500.0
The fourth digit from right is 7
Rounding to it, as it has 5 next to it, the rounded version will make 7500 -> 8000
Thus, we get:
347500 -> 348000
Similarly,
There are 5 digits in 10000, and 5th digit from right in 347500 is 4
Right to 4, there is 7, which is ≥ 5, therefore, 47500 will become 50000
Thus, we get:
347500 -> 350000
6th digit from right in 347500 is 3.
Right to 3 lies 4. 4 < 5 therefore 347500 will become 300000 after rounding to the nearest 100000
The digit 5 acts as a limit.
If the right sided digit to the digit where we've to round off is < 5, we keep it same and make all right sided values 0, and if the right sided digit is > 5, then we make it increase by 1 and rest of the right sided digits become 0. If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
Thus, the rounded form of 347500 for given cases gives 348000, 350000 and 300000.

Answer and Step-By-Step-Explanation:
Expanded form is stating all place values of a number and separating it.
So we have 3.611
3 is the ones place
3
There is a decimal point following before the number 6
Which is in the tenths place
3 + 0.6
After that, there is a 1
In the hundredths place
3 + 0.6 + 0.01
Lastly, there is another 1
In the thousandths place
3 + 0.6 + 0.01 + 0.01
Answer:
11x² - 3x
Step-by-step explanation:
Here's one way to do it. Write the two polynomials with corresponding powers of x under each other and subtract.
12x² - 5x
-(x² - 2x)
Distribute the -1 and add.
12x² - 5x
-x² + 2x
11x² - 3x
Check:
x² - 2x
+(11x² - 3x)
12x² - 5x
OK.
