6x^2 + 37x - 60 = 6x^2 - 8x + 45x - 60 = 2x(3x - 4) + 15(3x - 4) = (3x - 4)(2x + 15)
-2 + 8 = 6
because if you have 2 negative circles ●● and 8 positive circles ○○○○○○○○ then once you take away the first two circles you get you answer. You do the opposite. :) ( hope that make sense... )
<span>The dependent variable is the value that changes when one factor is changed. The independent variable is what being changed in a system. For this cae the dependent variable would be the height of the parasail while the independent variable would be the speed of the motorboat.</span>
Please tell me what’s the question. So I can answer.
Answer: His total rental cost will be $164.75.
Step-by-step explanation:
Since we have given that
Cost of per day = $30
Cost of per mile after the first 100 miles = $0.65
According to question, he was travelling 215 miles in 3 days.
So, it becomes,
![30\times 3+0.65\times (215-100)\\\\=90+0.65\times 115\\\\=90+47.75\\\\=\$164.75](https://tex.z-dn.net/?f=30%5Ctimes%203%2B0.65%5Ctimes%20%28215-100%29%5C%5C%5C%5C%3D90%2B0.65%5Ctimes%20115%5C%5C%5C%5C%3D90%2B47.75%5C%5C%5C%5C%3D%5C%24164.75)
Hence, his total rental cost will be $164.75.
