If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:
a = ?
(x + 9) * (x + a) = <span>(x^2 + 5x - 36)
x^2 + ax + 9x + 9a = x^2 + 5x - 36
ax + 9x = 5x
a + 9 = 5
a = 5 - 9
a = - 4
The correct result would be x - 4.

Answer: 7725 square feet
----------------------------------------------------------------------------------------------
Explanation:
Step 1 is to add the two parallel bases together: 125+81 = 206. Afterwards, divide that by 2 to get 206/2 = 103. The last thing to do is multiply that result by the height to get 103*75 = 7725

I think i did it wrong but 1980 is what i got...i am unsure. hope that helped though:)
That is because there are many quadratic functions that have the same axis of symmetry. If a function is multiplied by a constant factor the axis of symmetry remains the same but the curved part of the graph widens or narrows.
For example x^2 + x - 6 and 2x^2 + 2x - 12 The last function will have same axis of symmetry and same roots as the first but the curved part will be narrower.
Also if we multiply the first function by -1 the curve will flip about the x axis but will have the same axis of symmetry
