The sum of two numbers is 41 and their difference is 5. what are their differences

18 and 23. I found this answer using the guess and check method. Since the difference is only five, the two numbers are around half of 41. I began by finding the numbers around 20 that were five apart.

I got 18 and 23.. firstly I tried numbers around 20(since half of 40 is 20) then I worked my way It took me around 5-10 mins (yes I'm a slow mathematician)

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
