I would say 28 square inches. Imagine that we divide the number and we get 4 and seven. your average paperback book is about 4 inches wide and 7 inches tall. If we multiply it back, we get 28 square inches.
Hope it helps!

Answer:
and ![\frac{-2-7\sqrt{2} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2-7%5Csqrt%7B2%7D%20%7D%7B2%7D)
Step-by-step explanation:
<em>hey there,</em>
<em />
< The way you solve right angle triangle problems are using the Pythagorean theorem. (I hope you have already learned it but if you haven't feel free to ask me.)
Pythagorean theorem states: ![a^2 + b^2 = c^2](https://tex.z-dn.net/?f=a%5E2%20%2B%20b%5E2%20%3D%20c%5E2)
The two sides of the triangle that touch the right angle are (x+5) and (x-3).
Those two values count as "a" and "b". "c" would be 9.
Let's put them into the equation now.
![(x+5)^2 + (x-3)^2 = 9^2](https://tex.z-dn.net/?f=%28x%2B5%29%5E2%20%2B%20%28x-3%29%5E2%20%3D%209%5E2)
Simplify:
![(x^2 + 10x + 25) + (x^2-6x+9) = 81](https://tex.z-dn.net/?f=%28x%5E2%20%2B%2010x%20%2B%2025%29%20%2B%20%28x%5E2-6x%2B9%29%20%3D%2081)
![2x^2 + 4x + 34 = 81](https://tex.z-dn.net/?f=2x%5E2%20%2B%204x%20%2B%2034%20%3D%2081)
![2(x^2+2x+17) = 81\\x^2+2x+17 = \frac{81}{2}](https://tex.z-dn.net/?f=2%28x%5E2%2B2x%2B17%29%20%3D%2081%5C%5Cx%5E2%2B2x%2B17%20%3D%20%5Cfrac%7B81%7D%7B2%7D)
![x^2 +2x+ (17-\frac{81}{2})=0\\ x^2+2x+(\frac{-47}{2}) = 0\\](https://tex.z-dn.net/?f=x%5E2%20%2B2x%2B%20%2817-%5Cfrac%7B81%7D%7B2%7D%29%3D0%5C%5C%20x%5E2%2B2x%2B%28%5Cfrac%7B-47%7D%7B2%7D%29%20%3D%200%5C%5C)
From there, you can solve to x (it might be a little tricky, so sorry if you don't understand these steps).
![2x^2 + 4x - 47 = 0\\\frac{-b ±(\sqrt{b^2-4ac})}{2a}](https://tex.z-dn.net/?f=2x%5E2%20%2B%204x%20-%2047%20%3D%200%5C%5C%5Cfrac%7B-b%20%C2%B1%28%5Csqrt%7Bb%5E2-4ac%7D%29%7D%7B2a%7D)
final answer:
and

It is in the hundreds place.
The type of transformation that preserves the symmetry is Vertical translation.
For instance, a parabola is still symmetric about the y-axis if you move it up. It loses its symmetry if you move it to the left or right. Reflection keeps both even and odd functions symmetrical.
<h3>
What is the difference between even and odd function ?</h3>
The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin
. This means that if you rotate an odd function 180 degrees around the origin, the function you started with will still exist.

Answer: 32 buttons
Step-by-step explanation:
Matt has 11 white buttons.
Matt has 9 fewer brown buttons than white buttons. This means he has (11 -9) = 2 brown buttons
Matt has 17 more grey buttons than brown buttons. This means that he has (2 + 17) = 19 grey buttons.
The total number of buttons that Matt has will be;
= 11 white + 2 brown + 19 grey
= 32 buttons
