Answer:
A = 1, B = 1
Step-by-step explanation:
From the question
(2x+1)/(x²+x) = A/x + B/(x+1)
(2x+1)/(x²+x) = [A(x+1)+(Bx)]/(x²+x)
Equation the numerator
2x+1 ≡ A(x+1) +Bx
2x+1 ≡ Ax+A+Bx
From the above,
A = 1.
And,
2x = Ax+Bx................ Equation 1
A+B = 2
Substitute the value of A into Equation 1
1+B = 2
B = 2-1
B = 1
I think its x^2(18x^2 -9+4x) sorry if I’m wrong
7(x-1)
You need to provide an "equals" in order to find what x equals
Answer:1.97
87.2º
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
