We have to find the quotient :
( 4 x³ y + 12 x² y³ - 20 x y ) / ( 4 x y ) =
= 4 x y ( x² + 3 x y² - 5 ) / ( 4 x y ) = ( Then 4 x y will be cancelled )
= x² + 3 x y² - 5
Answer:
D ) x² + 3 x y² - 5
All that is necessary in this question is to divide. 240 km divided by 12 is 20. So this means that it would take exactly 20 hrs for someone to drive 240 km in 12 km an hr<span />
The formula is pi/180! 10 divided by 180 is 18 so I think the answer is pi/18 check on calculator first to be sure
