The answer would be 8 although, if you have to show work I can't help you.. I'm trying to help but I haven't learned percentage yet so I am using my percentage calculator.
Answer:
Solution given:
For 1st
x²=71
For x=±
and
For 2nd
x³=71
For x=±![\sqrt[3]{71}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B71%7D)
So answer is:
In first row
<u>Solution to x²=71</u>
In second row
<u>Solution to </u><u>x³</u><u>=71</u>
In third row
<u>neither</u>
In forth row
<u>Solution to x³=71</u>
Do them backwards and you will get the answer
360=24%0f x
360=24/100*x
360*100=24x
36000/24=x
therefore, x=1500......
y = 7/6.....................
