Answer:
The answer is 40.
Explanation:
First you find the coordinates of both r and s. The coordinates are R coordinates. (-20 1/2 , 5) S coordinates (20,5). Since we have that written down next we have to add both -20 and 20. Before adding them you have to switch -20 to positive 20. Now you have 20 + 20. giving you 40. Since it says to put the whole number you put 40.
Please tell me if is right or wrong. Ty. Also the other one is false I tried it and got it wrong and because of that one answer I failed my exam.
