Answer:
B.) 36/60
Step-by-step explanation:
some
equivalent fractions of 9/15:
3/5 = 6/10 = 9/15 = 12/20 = 15/25 = 18/30 = 21/35 = 24/40 = 27/45 =	30/50 = 33/55 = 36/60

 Answer:
Midpoint of AB              = (0 + 2a / 2 , 0 + 0 / 2) = (2a / 2 , 0 / 2) = (a,0)
x coordinate of point c = a 
                                   N = (0 + a / 2 , 0 + b / 2) = (a / 2 , b / 2)
                                   M = ( 2a + a / 2 , 0 + b / 2) = (3a / 2 , b / 2)
                                 MA = √(3a / 2 - 0)² + b / 2 - 0)²
                                        = √(3a / 2 )² + (b / 2) = 9a² / 4 + b² / 4
                                 NB = √(a / 2 - 2a)² + (b / 2 - 0 )²
                                       = √( a / 2 - 4a / 2)² + (b / 2 - 0)²
                                       = √(-3a / 2)² + (b / 2)² = √9a² / 4 + b² / 4

I tried my best hope its correct :0
 
        
             
        
        
        
-9x(5 - 2x)     Distribute/multiply 9x into (5 - 2x)
(-9x)5 - (-9x)2x
-45x - (-18x²)    2 negative signs cancel each other out and become +
-45x + 18x²    Your answer is A ( the first option)
