There is no common factor between 15, 17 and 18 because 17 is prime.
15z² +17z - 18 =
d = 17² - 4.15.-18
d = 289 + 1080
d = 1369
z = (-17 +/- \/1369) : 2 * 15
z = (-17 + 37) : 30
z' = 20 : 30 = 2/3
z" = (-17 - 37) : 30
z" = -54 : 30 = -1.8

Answer: 
Step-by-step explanation:
Given: Original length = 
inches
inches ( In improper fraction )
Length of piece cut from original = 
inches
inches ( In improper fraction )
Length of piece leftover piece = (Original length ) - (Length of piece cut )
Hence, the leftover piece will be long.

Answer:
$80000
Step by step explanation:
start by adding all the ratios.
2+3+4=9
next devide $360000 by 9
that should give you $40000
then look at the smallest ratio with is 2 which means you must double the amount.
so that means $40000x2= $80000
$80000 is your answer
hope this helps!
