Answer:

Step-by-step explanation:
- Since 2 opposite add up to 0,remove them from the expression (+4ab, - 4ab)
2. Calculate the product
The answer for PA is 60/13. This is found by
The area of the rectangle is 60, therefore, the big triangle areas are 30 each. We know that the hypotenuse is 13, so therefore, we get
1/2(13*PA) = 30. This then simplifies to
13 * PA = 60, which then turns into
PA = 60/13.
Hope this helps and have a nice day:)
