Please simplify the difference!: ((x^2+2x+8)/(x^2-3x-10)) - ((x^2-2x-3)/(x^2+7x-6)) Please don't just give me the answer, I actually want to know how to do problems like this--the material the entire course was based on was taught using the learning style I cannot work with whatsoever and I retained none of it. This is more of a study question for me than anything. Please help.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

answer is b

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
