Answer:
<h2><em>ΔE =12.3 - (-9.6) which is equivalent to 21.9 feet </em></h2>
<em />
Step-by-step explanation:
Give the distance covered by Vivian at the bottom of the elevation to be -9.6 feet and the distance covered by Vivian at the top of the elevation to be 12.3 feet, Vivian's change in elevation will be expressed as the difference in the elevation at the bottom and the elevation at the top.
Let the initial elevation Ei = -9.6 feet
Final elevation Ef = 12.3 feet
Change in elevation ΔE = Ef - Ei
Change in elevation ΔE =12.3 - (-9.6)
Change in elevation ΔE = 12.3 + 9.6
Change in elevation ΔE = 21.9 feet
<em>Hence the expression to represent Vivian's change in elevation from -9.6 feet at the bottom of the Ferris wheel to 12.3 feet at the top is </em><em>ΔE =12.3 - (-9.6) which is equivalent to 21.9 feet </em>

I like to always factor out the negative first, so that we will have our first term be positive:
So it can be rewritten as this: -(x^2-3x-28)
Then we need to find two numbers that multiply to -28, but add up to -3.
Those two numbers are -7 and +4.
So we can rewrite as: -(x-7)(x+4)
The diagonal of any square always occurs in a ratio of
relative to the square's sides. That means if
is the side length, then
gives the length of the diagonal. It follows that
.
Then the area of the square is
