answers: 1,2,12,24,42,106

The answers are as follows: 12 106 42

Step-by-step explanation:

Given:  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate separately and separately and add them. So we have .

Now for the second question: . we would get

Next, . This could be written as:  . Hence the answers.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
