8x²-18xy-5y²
8x²+2xy-20xy-5y²
2x(4x+y) -5y (4x+y)
= (2x-5y) (4x+y)
2 committees. 6 is divisible by 3 twice, 8 is divisible by 4 twice.
He would have to mow 14 lawns. To find the answer you would multiply 249.99 by 6%, then add the answer and round and you would get 264.99. 20 x 14 equals $280, so if he mowed 14 lawns and get $20 per lawn, he would buy the Mp3 and still have 15.01 leftover.
Hope this helps!
Answer: 3 + 15/16 inches
Step-by-step explanation:
You need (5 + 3/16) inches, and you have (9 + 1/8) inches, then the amount that you need to cut is equal to the difference between these numbers, this is:
(9 + 1/8) - (5 + 3/16) = (9 - 5) + (1/8 - 3/16) = 4 + (2/16 - 3/16) = 4 - 1/16
now, this notation is used for aditions, so we can write it as:
4 - 1/16 = 3 + 1 - 1/16 = 3 + 16/16 - 1/16 = 3 + 15/16
Then the amount that needs to be cuted is 3 + 15/16 inches
It is called parallel lines when there is two line that never intersect
