Lets say the price of a shirt is X, then the price of sweater is X + 3.95

Since a total cost is 71.65 for 3 shirts and 2 sweaters. 71.65 = (3*X) + 2*(X+3.95)

So, 71.65 = 3X + 2X + 7.9

71.65 - 7.9 = 5X

12.75 = X. Therefore, the price of a shirt is 12.75 dollars, and the price of a sweater is 16.7 dollars (12.75 + 3.95)

X^ 3 +x^ 2 +4x/x^ 2 +x-2<br>into partial<br>fractions​
lawyer [7]

Answer:

x + (4/ x-2) + (2/ x-1)

Step-by-step explanation:

x + (6x/ x^2 + 2x - x -2)

x + (6x/ (x + 2) X (x - 1))

(6x/ (x + 2) X (x - 1))

(A/ x+2) + (B/ x-1)

(6x/ (x + 2) X (x - 1)) = (A/ x+2) + (B/ x-1)

6x = Ax + Bx - A + 2B

6x = (A+B)x + (-A+2b)

{0 = -A+2B

{6 = A+B

(A,B) = (4, 2)

(4/ x+2) + (2/ x-1)

x + (4/ x-2) + (2/ x-1)

What is the sum of n natural numbers: 1+2+...+n?
r-ruslan [8.4K]

If

S=1+2+\cdots+(n-1)+n

then we also have

S=n+(n-1)+\cdots+2+1

Pairing up the terms, we can find that

2S=(1+n)+(2+n-1)+\cdots+(n-1+2)+(n+1)

2S=(n+1)+(n+1)+\cdots+(n+1)+(n+1)

S consists of n terms, so there are n copies of n+1 in the sum 2S. Then we find an immediate closed form for the sum:

2S=n(n+1)\implies S=\dfrac{n(n+1)}2
