The simplification of the expression (h² + 9·h - 1) × (-4·h + 3), involves the
multiplication of the terms. The error is therefore;
3. Calculating errors when distributing -1
<h3>How can the error in the calculation be found?</h3>
The expansion of (h² + 9·h - 1) × (-4·h + 3), is given as follows;
(h² + 9·h - 1) × (-4·h + 3) = -4·h³ + 3·h² - 36·h² + 27·h + 4·h - 3
Which gives;
-4·h³ - 33·h² + 31·h - 3
The calculation is therefore;
![\begin{array}{|c|c|c|c|}&h^2&+9 \cdot h & -1\\-4 \cdot h&-4\cdot h^3&-36\cdot h^2 &4 \cdot h\\+3& 3 \cdot h^2&27 \cdot h&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7Cc%7Cc%7C%7D%26h%5E2%26%2B9%20%5Ccdot%20h%20%26%20-1%5C%5C-4%20%5Ccdot%20h%26-4%5Ccdot%20h%5E3%26-36%5Ccdot%20h%5E2%20%264%20%5Ccdot%20h%5C%5C%2B3%26%203%20%5Ccdot%20h%5E2%2627%20%5Ccdot%20h%263%5Cend%7Barray%7D%5Cright%5D)
The error is therefore, in the distribution of the -1
The correct option is;

Answer: 
Step-by-step explanation:
For this exercise it is important to remember that, by definition, the length of the minor arc can be calculated wih the following formula:

In this case , according to the data given in the exercise, you know that:

Therefore, susbtituting those values into the formula, you get that length of AB is the following:
