You see how these 2 angles marked are both inside the 2 parallel lines?
And they are on opposite side of the transversal, the line crossing the 2 parallel lines?
These 2 angles are alternate interior angles and they are equal, I think you can do the last part by yourself.
Hey there :)
( 5y + 9 )( 6y - 1 )
We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms
First Outer Inner Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
30y² - 5y + 54y - 9
Combine, if any, the like-terms
30y² + 49y - 9
The answer is (x+5)(x-8)
Hope this helps
For a non-resident:
For a resident:
We want to know the number of days 
such that the two costs are equal ie 
To do this set the two costs equal to each other:
And solve for d:
The costs will be equal when a resident and a non-resident each use the beach for 12 days.
