Factor 15z^2+17z-18 please show work
siniylev [52]

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

What is the percent of discount on a $44 video game on sale for $28.60
Agata [3.3K]

Answer:

35% discount.

Step-by-step explanation:

28.60 / 44 = 13/20

13/20 = 65/100 = 65%

28.60 is 65% of 44

100 - 65 = 35

Therefore, the discount is 35%.
