A cube has 6 faces, and since it is a cube, all of them are the same. To find the area, we square the side of the square. A = 2.5^2 = 6.25 sq ft. Hope this helps.
Answer:
The answer is below:
Step-by-step explanation:
Rewrite: y(y−10)+30=0 into
y^2-10y+30
Quadratic formula:

Given:
The polynomial function is

Yuri thinks that
is a root of the given function.
To find:
Why
cannot be a root?
Solution:
We have,

If
is a root, then the value of the function at
is 0.
Putting
in the given function, we get




Taking LCM, we get


Since the value of the function at
is not equal to 0, therefore,
is not a root of the given function.
2/3 is equal to 4/6 When multiplied by 2/2. You can do this because 2/2 is still equal to one so it doesn’t change the value, just how it looks
