Answer:

Step-by-step explanation:
If the point (2,3) is on the terminal side of an angle in standard position.
Adjacent of O, x=2, 
Opposite of O, y=3
Next, we determine the hypotenuse, r using Pythagoras Theorem.

Therefore:



 
        
             
        
        
        
<span>10x2y(2x + 3y)
Each term has 10 in it. Plus each term has at least 2 x's and 1y. The parenthesis are what's left over. </span>
        
             
        
        
        
4/5 (20x - 10)...use distributive property...basically multiplying the 4/5 by everything in the parenthesis,
4/5 * 20x - 4/5 * 10 =
16x - 8
