Hi there!
5 + 5 = 10
Hope this helps and good luck! :)
The formula for the area of a square is:
A=s²
Since we known that the area is 81ft², we can solve for the length of a side.
A=s²
81=s²
find the square root of both sides
9ft=s
The length of each side is 9ft
For this case we have the following number:
57
We can write this number in the form of a word.
Therefore, we are giving it a different name.
By writing the number in the form of a word we have:
57: fifty-seven
Answer:
An equivalent name for the number 57 is given by:
fifty seven
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:
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)
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.
