Answer:
169
Step-by-step explanation:
becuse it is just L * W
The range = highest value - lowest = 86 - 13 = 73.
arrange in order:-
13 42 45 46 47 74 86
median = 46
First quartile = (42 + 45) / 2 = 43.5
third quartile = (74 - 47) / 2 = 60.5
Answer:
the curved area would be 396cm^2
Answer:
<em>-13x +8y</em>
Step-by-step explanation:
-5x+2y-8x+6y
rearranging;
-5x-8x+2y+6y
(-5x-8x)+(2y+6y)
(-13x)+(8y)
Solution:
we have been asked to find the solution of the equation

It can be solved using factoring as below:
![x^6 + 6x^3 + 5 = 0\\\\substitute, x^3=y\\\\y^2+6y+5=0\\\\y^2+5y+y+5=0\\\\y(y+5)+1(y+5)=0\\\\(y+5)(y+1)=0\\\\y=-1,-5\\\\\text{substitute back }y=x^3\\\\x^3=-1,-5\\\\x=-1,\sqrt[3]{-5} \\\\\text{These are the only real solutions}\\](https://tex.z-dn.net/?f=x%5E6%20%2B%206x%5E3%20%2B%205%20%3D%200%5C%5C%5C%5Csubstitute%2C%20x%5E3%3Dy%5C%5C%5C%5Cy%5E2%2B6y%2B5%3D0%5C%5C%5C%5Cy%5E2%2B5y%2By%2B5%3D0%5C%5C%5C%5Cy%28y%2B5%29%2B1%28y%2B5%29%3D0%5C%5C%5C%5C%28y%2B5%29%28y%2B1%29%3D0%5C%5C%5C%5Cy%3D-1%2C-5%5C%5C%5C%5C%5Ctext%7Bsubstitute%20back%20%7Dy%3Dx%5E3%5C%5C%5C%5Cx%5E3%3D-1%2C-5%5C%5C%5C%5Cx%3D-1%2C%5Csqrt%5B3%5D%7B-5%7D%20%5C%5C%5C%5C%5Ctext%7BThese%20are%20the%20only%20real%20solutions%7D%5C%5C)
