Answer:
<em>the answer is c</em>
( 2 x + 3 y ) ( 2 x − 3 y ) is the factored form of the expression
Step-by-step explanation:
- 4 x 2 − 9 y 2 can be also written as ( 2 x ) 2 − ( 3 y ) 2
- Now, as per identity: a 2 − b 2 = ( a + b ) ( a − b )
- So , in case of our expression a = 2 x , b = 3 y ( 2 x ) 2 − ( 3 y ) 2 = ( 2 x + 3 y ) ( 2 x − 3 y )

<span>This can be represented by the equation d = 35 + 45x, where d is the distance from the terminal and x is hours of travel. At the beginning of the journey the train had travelled 0 hours, so x = 0. Therefore, d = 35 + (45 x 0). D = 35 + 0. The train is 35 miles from the terminal.</span>
