X ^ 2 - 9
= x ^ 2 - 3 ^ 2
It turns into 3 ^ 2
Because 3 ^ 2 = 9
The final answer is
= ( x + 3 )( x - 3 )
remember the formula :
a^2 - b^2 =(a+b)(a-b)
72-63=9
9/72=13%
13% IS .13 SO TENTH IS .1
I AM NOT SURE ABOUT THE TENTH
Answer:
It would be all of the above.
Step-by-step explanation:
An example of a polynomial is:
2x^3 - 4x^2 +1x -8
Note how there are exponents, such as ^3 for example. There is also a variable, in this case x. Lastly, there are constants, which are numbers by themselves.
The inequality is given by 20x + 25y ≤ 1100 and x + y > 50
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let y represent the number of soccer balls and x represent the number of volleyballs.
The coach can spend a maximum of $1,100, hence:
20x + 25y ≤ 1100
Also, The coach plans to order at least 50, hence:
x + y > 50
The inequality is given by 20x + 25y ≤ 1100 and x + y > 50
