(X+5)^2 = x^2 +10x + 25
the expression that is equivalent to
To multiply it we apply FOIL method
Multiply x with x+5 first and then we multiply 5 with x+5
Answer: ![\sqrt{2}a-\sqrt{3}a-2\sqrt{a}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7Da-%5Csqrt%7B3%7Da-2%5Csqrt%7Ba%7D)
Step-by-step explanation:
![\lim _{x\to \:a}\left(\sqrt{2}x-\sqrt{3}x-\frac{a}{\sqrt{x}}-\sqrt{a}\right)](https://tex.z-dn.net/?f=%5Clim%20_%7Bx%5Cto%20%5C%3Aa%7D%5Cleft%28%5Csqrt%7B2%7Dx-%5Csqrt%7B3%7Dx-%5Cfrac%7Ba%7D%7B%5Csqrt%7Bx%7D%7D-%5Csqrt%7Ba%7D%5Cright%29)
![=\sqrt{2}a-\sqrt{3}a-\frac{a}{\sqrt{a}}-\sqrt{a}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B2%7Da-%5Csqrt%7B3%7Da-%5Cfrac%7Ba%7D%7B%5Csqrt%7Ba%7D%7D-%5Csqrt%7Ba%7D)
![=\sqrt{2}a-\sqrt{3}a-2\sqrt{a}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B2%7Da-%5Csqrt%7B3%7Da-2%5Csqrt%7Ba%7D)
M=30/22,5=1,33
m=25/x=1,33. ...>x=25/1,33=18,7
Convert into like fractions -->
1/3 = 7/21 4/7 = 12/21
7+12 = 19
19/21 is spent therefore he has 2/21 left
The answer is 243 is the answer to this question
