Answer:
D. ![\frac{x-1}{x^2+3x+2}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7Bx%5E2%2B3x%2B2%7D%7D)
Step-by-step explanation:
The given expression is;
![\frac{x}{x^2+3x+2}-\frac{1}{(x+2)(x+1)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%5E2%2B3x%2B2%7D-%5Cfrac%7B1%7D%7B%28x%2B2%29%28x%2B1%29%7D)
This is the same as;
![\frac{x}{(x+2)(x+1)}-\frac{1}{(x+2)(x+1)}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B%28x%2B2%29%28x%2B1%29%7D-%5Cfrac%7B1%7D%7B%28x%2B2%29%28x%2B1%29%7D)
The denominators are the same.
Subtract the numerators and write one denominator;
![\frac{x-1}{(x+2)(x+1)}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7B%28x%2B2%29%28x%2B1%29%7D%7D)
Rewrite to get;
![\frac{x-1}{x^2+3x+2}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-1%7D%7Bx%5E2%2B3x%2B2%7D%7D)
Answer:
44⁰.
Step-by-step explanation:
Its supplement = 180 - 136
= 44 degrees.
The size of the large cabinets door = 2.3 * 11.5 = 26.45 inches
the board size in inches = 10 1/2 * 12 = 126 inches
number of doors = 126 / 26.45 = 4.76
so the number of doors = 4 doors
