Y-intercept: -5
slope: 6/2 = 3
equation of line: y = 3x - 5
inequality: y > 3x - 5
Area of a circle is pi x r^2
R = d/2 = 14.2 = 7
Area = 3.14 x 7^2
Area = 3.14 x 49
Area = 153.86 round to 154
Answer is 154 square feet.
To create a perfect square trinomial, halve the x coefficient, square it, and then add that value.
In the case of x² + 6x, we would have 6 to get 3, then square 3 to get 9.
We would add 9 to make a perfect square trinomial.
<u>
</u><u>Why this works</u>
A perfect square trinomial is designed to factor to some value (x+n)².
When you FOIL this you get x² + 2nx + n².
As you can see, if you wanted to find the value of that n², you could take that x coefficient 2n, halve it to get n, and then square it to get n²!
