Answer:
40ft
Step-by-step explanation:
Add up all four sides of your rectangle:
15ft + 15ft +5ft + 5ft = 40ft
You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.
Answer & Explanation:
First, divide the nominal rate by the number of compounding periods. The result is the periodic rate. Now add this number to 1 and take the sum by the power of the number of compounding interest rates. Subtract 1 from the product to get the effective interest rate.
Answer: the 5 in the parentheses on the second line should be negative. Also, where did the 23 go?? That's a mistake too.
Step-by-step explanation: 3 - 8 = -5 so
23(2 - 4) + 5(3 - 8)
23(-2) + 5(-5)
(-46) + (-25)
-71
(at least, I think so unless there was a mistake in the equation)
Answer:
The simplified expression to the given expression is 
Therefore 
Step-by-step explanation:
Given fractional expression is 
To simplify the given expression as below :
![=\frac{2[(2)^4(x^3)^4(y^4)^4]}{(2)^3(x^2)^3(y^6)^3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%5B%282%29%5E4%28x%5E3%29%5E4%28y%5E4%29%5E4%5D%7D%7B%282%29%5E3%28x%5E2%29%5E3%28y%5E6%29%5E3%7D)
( using the property 
)
![=\frac{2[(2)^4(x^{12})(y^{16})]}{(2)^3(x^6)(y^{18})}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%5B%282%29%5E4%28x%5E%7B12%7D%29%28y%5E%7B16%7D%29%5D%7D%7B%282%29%5E3%28x%5E6%29%28y%5E%7B18%7D%29%7D)
^{-3}(x^{-6})(y^{-18})](https://tex.z-dn.net/?f=%3D2%5B%282%29%5E4%28x%5E%7B12%7D%29%28y%5E%7B16%7D%29%5D%282%29%5E%7B-3%7D%28x%5E%7B-6%7D%29%28y%5E%7B-18%7D%29)
( ( using the property 
)
![=2[2^{4-3}x^{12-6}y^{16-18}]](https://tex.z-dn.net/?f=%3D2%5B2%5E%7B4-3%7Dx%5E%7B12-6%7Dy%5E%7B16-18%7D%5D)
( using the property 
)
![=2[2^1x^6y^{-2}]](https://tex.z-dn.net/?f=%3D2%5B2%5E1x%5E6y%5E%7B-2%7D%5D)
( using the property )
Therefore the simplified expression is
Therefore
