Step-by-step explanation:
No,The room is not a square shaped.This is because.Perimeter of the square shape would be length of any sides×4 as all sides will be the same in a square.Therefore, if the room ia a square, the 4 sides of room floor will be equal too.It is not a square shaped room beacause it sides are not equal for floor.We can determine by finding the sides;
diagonal is 18.75 so by using pythagoras theorem
diagonal^2 =l^2 + b^2
b^2=18.75^2 + 17^2
b =25.31 inches which is not the same as the length 17 inches.Therefore,the room is not a square
Answer:
![Length =5](https://tex.z-dn.net/?f=Length%20%3D5)
![Width = 2](https://tex.z-dn.net/?f=Width%20%3D%202)
Step-by-step explanation:
Given
![Length =x](https://tex.z-dn.net/?f=Length%20%3Dx)
![Width = x -3](https://tex.z-dn.net/?f=Width%20%3D%20x%20-3)
![Area = 10](https://tex.z-dn.net/?f=Area%20%3D%2010)
![x(x-3) =10](https://tex.z-dn.net/?f=x%28x-3%29%20%3D10)
See comment for missing part of the question
Required
Complete the expression to determine the dimension of a rectangle
We have:
![x(x-3) =10](https://tex.z-dn.net/?f=x%28x-3%29%20%3D10)
Open bracket
![x^2 -3x = 10](https://tex.z-dn.net/?f=x%5E2%20-3x%20%3D%2010)
Equate to 0
![x^2 -3x - 10 =0](https://tex.z-dn.net/?f=x%5E2%20-3x%20-%2010%20%3D0)
Expand
![x^2 + 2x - 5x - 10 = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%202x%20-%205x%20-%2010%20%3D%200)
Factorize
![x(x + 2) - 5(x + 2) = 0](https://tex.z-dn.net/?f=x%28x%20%2B%202%29%20-%205%28x%20%2B%202%29%20%3D%200)
Factor out x + 2
![(x - 5)(x + 2) = 0](https://tex.z-dn.net/?f=%28x%20%20-%205%29%28x%20%2B%202%29%20%3D%200)
Solve for x
or ![x + 2 = 0](https://tex.z-dn.net/?f=x%20%2B%202%20%3D%200)
or ![x = -2](https://tex.z-dn.net/?f=x%20%3D%20-2)
The value of x cannot be negative
So:
![x = 5](https://tex.z-dn.net/?f=x%20%20%3D%205)
Recall that:
![Length = x](https://tex.z-dn.net/?f=Length%20%3D%20x)
![Width = x - 3](https://tex.z-dn.net/?f=Width%20%3D%20x%20-%203)
So:
![Length =5](https://tex.z-dn.net/?f=Length%20%3D5)
---- i.e. 5 - 3
Answer:
![5-6+11=-6+16=10](https://tex.z-dn.net/?f=5-6%2B11%3D-6%2B16%3D10)
Step-by-step explanation:
![5-6+11=-6+16=10](https://tex.z-dn.net/?f=5-6%2B11%3D-6%2B16%3D10)
Distinct angles are when the angles of a polygon are all different.
