The correct option regarding the error in calculating the length of segment AB is given as follows:
There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.
<h3>Where are points A and B?</h3>
Researching the problem on the internet, it is found that points A and B are on a number line, with coordinates given as follows:
<h3>What is the length of the segment?</h3>
The length of the segment is the absolute value of the subtraction of the endpoints, hence:
L = |4.5 - 1| = |1 - 4.5| = 3.5.
The error is that:
There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.

Answer:
13- No because the size of the triangle can be different, meaning bigger side length
in 14 he is forgetting the lines at the angles. The little circular ones that say the angles are congruent.

Step-by-step explanation:
Percentage of Fiction books
= 100% - 20% - 25%
= 55%
Number of Fiction books
= 55/100 × 140
= <u>7</u><u>7</u>

If lines through XY and YW form a 90° angle, so that Y is a right angle,
then the product of the slopes of the lines through XY and YW must be -1
let the slopes through X,Y and Y,W be
and
respectively
so
Right answer:
