Answer:
f(x) = 7/(x+3) -38/(x+3)²
Step-by-step explanation:
The denominator is a perfect square, so the decomposition to fractions will involve both a linear denominator and a quadratic denominator.
You can start with the form ...
... f(x) = B/(x+3) + A/(x+3)²
and write this sum as ...
... f(x) = (Bx +3B +A)/(x+3)²
Equating coefficients gives ...
... Bx = 7x . . . . . B = 7
... 3B +A = -17 . . . . the constant term
... 21 +A = -17 . . . . filling in the value of B
... A = -38 . . . . . . . subtract 21 to find A
Now, we know ...
... f(x) = 7/(x+3) -38/(x+3)²
Answer: 
Step-by-step explanation:
One-sixth of n is n/6.
One-fifth of g is g/5.
The sum means to add, so the expression is .

Sorry if this is wrong.
Answer:
a= 180-60-55=65
we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.
b=180-90-65=25
the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.
c=25
c is 25, because two angles on both sides of a X is the same
Answer:
Music is an art form that means individuals can consider what is music to them.
Music in the dictionary describes music as any sound or voice that produces beauty or form. What shapes body percussion in any percussion would be therefore its form or beauty, to be considered music.
If it fails to provide that quality then it is just considered sound or at best notation to music like a short sound can provide would also be notation to music.
