Answer:

Step-by-step explanation:
Given the rational expression:
, to express this in simplified form, we would need to apply the concept of partial fraction.
Step 1: factorise the denominator





Thus, we now have: 
Step 2: Apply the concept of Partial Fraction
Let,
= 
Multiply both sides by (x - 1)(x - 4)
= 

Step 3:
Substituting x = 4 in 





Substituting x = 1 in 





Step 4: Plug in the values of A and B into the original equation in step 2


I think that x may equal to -3. Because the sum of a triangle is always 180. 55+54=109 and 180-109=71 and -3+74=71
For functions, there is only many input values, but there can be only one output value, and there can be no identical x values. For this, x=3.2. If y= 2*3.2 - 1, then y=5.4.
Answer:
The answer is 4.
Step-by-step explanation:
Change 4 2/3 to 4 4/6 to match 11/6.
Add 4 4/6 and 11/6 and get 4 15/6.
Subtract 4 15/6 by 15/6 and get 4.
4 is the answer.
I hope this helps.
Have a nice day!
