16/2=8
8 * 8 = 64
64* 3.14 = 200.96
200.96 * 60 = 12057.6
I believe that is the right answer but i am not 100% sure let me know if i was wrong
334 is the answer to the question
They would have to have opposite slopes. ex: Y=2x+4 | Y=-1/2x+8 or if you are asking in general you could write. LINE AB | LINE CD
Whys u have to do is find a common denominator between 7/8 and 3/16. 8x2 equals 16 and what ever u do to the denominator u have to do to the numerator. So do 7x2 and u will get 14/16. For A it answer should be the 1st pic and the answer to number 2 is 14/16. Hope it helps! :)
