<span>If you cut the "whole" into 5 equal pieces, then 3/5ths would be 3 of those 5 pieces. so the answer is 3</span>
Answer:
x^2 -9
Step-by-step explanation:
(x + 3)(x − 3)
FOIL
first x*x =x^2
outer -3x
inner 3x
last -3*-3 =-9
Add together
x^2 -3x+3x -9
Combine like terms
x^2 -9
Answer:
2.5 times 60 equals 150. 150-78 equals 72. So the answer is 72.

Answer:
5.5
Step-by-step explanation:
0,2,3,3,4,5,6,7,8,8,9,9
there are to middle numbers
add then together (5 and 6)
which makes 11
divide 11 by 2

Answer:
No extraneous solution
Step-by-step explanation:
We have the logarithmic equation given by,
![\log_{2}[\log_{2}(\sqrt{4x})]=1](https://tex.z-dn.net/?f=%5Clog_%7B2%7D%5B%5Clog_%7B2%7D%28%5Csqrt%7B4x%7D%29%5D%3D1)
i.e. ![\log_{2}(\sqrt{4x})=2^{1}](https://tex.z-dn.net/?f=%5Clog_%7B2%7D%28%5Csqrt%7B4x%7D%29%3D2%5E%7B1%7D)
i.e. ![\sqrt{4x}=2^{2}](https://tex.z-dn.net/?f=%5Csqrt%7B4x%7D%3D2%5E%7B2%7D)
i.e. ![\sqrt{4x}=4](https://tex.z-dn.net/?f=%5Csqrt%7B4x%7D%3D4)
i.e. ![4x=4^{2}](https://tex.z-dn.net/?f=4x%3D4%5E%7B2%7D)
i.e. ![4x=16](https://tex.z-dn.net/?f=4x%3D16)
i.e. ![x=4](https://tex.z-dn.net/?f=x%3D4)
So, the solution of the given equation is x=4.
Now, as we domain of square root function is x > 0 and also, the domain of logarithmic function is
.
Therefore, the domain of the given function is x > 0.
We know that the extraneous solution is the solution which does not belong to the domain.
But as x=4 belongs to the domain x > 0.
Thus, x = 4 is not an extraneous solution.
Hence, this equation does not have any extraneous solution.
