$5,400
Step-by-step explanation:
Answer:
x= 9/20 = .45
Step-by-step explanation:
20x=9
x= 9/20 = .45
Division yields

Now for partial fractions: you're looking for constants <em>a</em>, <em>b</em>, and <em>c</em> such that


which gives <em>a</em> + <em>b</em> = 2, <em>c</em> = 0, and 2<em>a</em> = -7, so that <em>a</em> = -7/2 and <em>b</em> = 11/2. Then

Now, in the integral we get

The first two terms are trivial to integrate. For the third, substitute <em>y</em> = <em>x</em> ² + 2 and d<em>y</em> = 2<em>x</em> d<em>x</em> to get

Answer:
See below
Step-by-step explanation:
We want to prove that

Taking the RHS, note

Remember that

Therefore,

Once

Then,

Hence, it is proved
