What are the roots of the quadratic equation below 3x2+15x-5=0
fomenos

Answer:

<h2>A</h2><h2 />

Step-by-step explanation:

3x^2+15x-5=0\\a = 3\\b = 15\\c = -5\\ x = -b\±\frac{\sqrt{b^{2} -4ac} }{2a} \\x = -(15)\±\frac{\sqrt{15^{2} -4(3)(-5)} }{2(3)} \\x = -15 \±\frac{\sqrt{225+60} }{6} \\x = -15\±\frac{\sqrt{285} }{6} = A

The mechanic dose 4 oil changes in 2 hours. How many oil changes can the mechanic do in 8 hours HELLOOOO OLEASE HELP THIS IS DUE
Yuki888 [10]

Answer:

16 oil changes

Step-by-step explanation:

You can write this into ratio form to help explain this. The ratio 4:2 can be used to explain this problem with the 4 meaning 4 oil changes and the 2 meaning after every two hours. You want to make it to where the 2 hours is at 8 hours so you would multiply 4 on both sides of the ratio which will give you the new ratio of 16:8. The mechanic can do 16 oil changes within 8 hours.
