Yes it is a least 75 stories tall and.....
Total coins=46 There are 10 dimes, so it is 10/46. If you reduce it the answer is 5/23. That is not one of the visible options, but there is no option for B so I could be right!
Answer:
The numbers are -21 and 21
Step-by-step explanation:
Let
x ----> one number
y ----> another number
S----> the sum of their squares
we know that
![x-y=42](https://tex.z-dn.net/?f=x-y%3D42)
----> equation A
----> equation B
substitute equation A in equation B
![S=x^2+(x-42)^2](https://tex.z-dn.net/?f=S%3Dx%5E2%2B%28x-42%29%5E2)
![S=x^2+x^2-84x+1,764](https://tex.z-dn.net/?f=S%3Dx%5E2%2Bx%5E2-84x%2B1%2C764)
![S=2x^2-84x+1,764](https://tex.z-dn.net/?f=S%3D2x%5E2-84x%2B1%2C764)
This is the equation of a vertical parabola open upward
The vertex is a minimum
Find the coordinates of the vertex
Using a graphing tool
The vertex is the point (21,882) ----> see the attached figure
we have
x=21
<em>Find the value of y</em>
![y=x-42](https://tex.z-dn.net/?f=y%3Dx-42)
![y=21-42=-21](https://tex.z-dn.net/?f=y%3D21-42%3D-21)
therefore
The numbers are -21 and 21
