When you look at the expression, 54 + 27, what do the two addends have in common?The first thing I notice is that 54 = 2(27), which means that 27 is a factor of both. Since, 27 is actually one of the addends, it's the greatest factor of 27 and therefore the greatest common factor. So,54 + 27 = 27(2+1)54 + 27 = 27(3)

Step-by-step explanation:
A cube has 6 sides. Divide the surface area by 6 to get the area of one side:
13 1/2 /6 = 2 1/4
The area of one side is S^2
To fins the length of the sides find the square root of the area:
Side = sqrt(2 1/4)
Side = 1 1/2 cm.
Answer:
Descarte's rule says that the polynomial will have the number of zeroes equal to the number of times the sign off the coefficient changes.
For positive real roots:
![P(x)=9x^3-4x^2+10](https://tex.z-dn.net/?f=P%28x%29%3D9x%5E3-4x%5E2%2B10)
The coefficient of polynomial is:
+9 -4 +10
There is 2 time sign in changing in 1st and 2nd term and then in 2nd and 3rd term.
So,there will be 2 positive real roots or less but even.
For negative real roots find P(-x)
![P(-x)=-(9x^3-4x^2+10)](https://tex.z-dn.net/?f=P%28-x%29%3D-%289x%5E3-4x%5E2%2B10%29)
![P(-x)=-9x^3+4x^2-10](https://tex.z-dn.net/?f=P%28-x%29%3D-9x%5E3%2B4x%5E2-10)
So, coefficient of above polynomial is:
-9 +4 -10
There is 2 time sign in changing in 1st and 2nd term and then in 2nd and 3rd term.
So,there will be 2 negative real roots or less but even.
