Danielle's mistake was that he did not add the middle like-wise terms of 2x² and x² in step 3.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Subtract x³ - 2x² from x² - 6
Danielle's mistake
⇒ (x³ - 2x²) - (x² - 6)
⇒ x³ - 2x² - x² + 6
⇒ x³ - 2x² + 6
He wrote 2x² instead of 3x²,
Danielle's mistake was that he did not add the middle like-wise terms of 2x² and x² in step 3.
Here is the Correct work as:
⇒ (x³ - 2x²) - (x² - 6)
⇒ x³ - 2x² - x² + 6
⇒ x³ - 3x² + 6

A. 2.4971.1 in because that is the biggest number compared to all of the others which will make it the tallest and closest to the surface of the yoga ball.
To add two three digits number to form a three digit number, the 3 digit number to be added should be less than 500 because 500 + 500 gives 1000 which is a four digit number.
In this case, there are many possibilities of creating a three digit number from 2 three digit number.
Example :
462 + 395 = 857
200 + 350 = 550
1. 44
2. 126.854
3. 9 5/12
