Answer:
Third option: 12x^2+8x+25
Step-by-step explanation:
s1=8x^2
s2=4x^2+15
s3=8x+10
Total perimeter of the pool edge: P
P=s1+s2+s3
Replacing s1, s2 and s3 in the formula above:
P=(8x^2)+(4x^2+15)+(8x+10)
P=8x^2+4x^2+15+8x+10
Adding like terms:
P=12x^2+8x+25
Answer:
tanx + cotx = ![\frac{1}{sinxcosx}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bsinxcosx%7D)
Step-by-step explanation:
<u><em>Explanation</em></u>
Take R.H.S = ![\frac{1}{sinxcosx}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bsinxcosx%7D)
= ![\frac{sin^{2}x+cos^{2}x }{sinxcosx}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%5E%7B2%7Dx%2Bcos%5E%7B2%7Dx%20%20%7D%7Bsinxcosx%7D)
= ![\frac{sin^{2}x }{sinx cosx} + \frac{cos^{2} x}{sinxcosx}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%5E%7B2%7Dx%20%7D%7Bsinx%20cosx%7D%20%2B%20%5Cfrac%7Bcos%5E%7B2%7D%20x%7D%7Bsinxcosx%7D)
= ![\frac{sinx}{cosx} + \frac{cosx}{sinx}](https://tex.z-dn.net/?f=%5Cfrac%7Bsinx%7D%7Bcosx%7D%20%2B%20%5Cfrac%7Bcosx%7D%7Bsinx%7D)
= tanx + cotx
tanx + cotx = ![\frac{1}{sinxcosx}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bsinxcosx%7D)
