Kaylas piece is not heavier, is this a trick question?
Answer:
9 units
Step-by-step explanation:
Given
![Length = 8](https://tex.z-dn.net/?f=Length%20%3D%208)
![Width = 4](https://tex.z-dn.net/?f=Width%20%3D%204)
![Height = 1](https://tex.z-dn.net/?f=Height%20%3D%201)
Required
Determine the length of the longest segment
To do this, we use:
![Longest = \sqrt{Length^2 + Width^2 + Height^2}](https://tex.z-dn.net/?f=Longest%20%3D%20%5Csqrt%7BLength%5E2%20%2B%20Width%5E2%20%2B%20Height%5E2%7D)
So, we have:
![Longest = \sqrt{8^2 + 4^2 + 1^2}](https://tex.z-dn.net/?f=Longest%20%3D%20%5Csqrt%7B8%5E2%20%2B%204%5E2%20%2B%201%5E2%7D)
![Longest = \sqrt{64 + 16 + 1}](https://tex.z-dn.net/?f=Longest%20%3D%20%5Csqrt%7B64%20%2B%2016%20%2B%201%7D)
![Longest = \sqrt{81}](https://tex.z-dn.net/?f=Longest%20%3D%20%5Csqrt%7B81%7D)
Take positive square root
![Longest = 9](https://tex.z-dn.net/?f=Longest%20%3D%209)
<em>Hence, the length of the longest segment is 9 units</em>
Answer:
AB = 5
Step-by-step explanation:
Since the triangle is isosceles then the legs are congruent, that is
BC = BA, substitute values
5x - 10 = 3x - 4 ( subtract 3x from both sides )
2x - 10 = - 4 ( add 10 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
AB = 3x - 4 = 3(3) - 4 = 9 - 4 = 5
(+8)+(-9)
the answer is -1
I think it’s 9 x (-7)(2) which equals -126
