  1. do things just as you would with numbers:

    (2+5)(7-3)
    2*7 + 5*7 - 2*3 - 5*3

    You have

    (n^3+8)(n-4)
    n^3*n + 8*n - n^3*4 - 8*4
    now simplify each term
    n^4 + 8n - 4n^3 - 32
    and arrange in descending powers
    n^4 - 4n^3 + 8n - 32

    Sometimes you may have several terms with the same power. In that case, collect them into a single term. For example,

    n^3 - 2n^2 + 3 + 9n^2 - 2n + 3 - 4n
    would become simply
    n^3 + 7n^2 - 6n + 6

    Solve the inequality. n-1/3n < n-4/3n-4 (it's actually less than or equal to) My first instinct is to multiply 3n, but that'll just give me squares and makes it harder to solve. I also thought about getting a common denominator,

    Multiply and simplify 2/3*13 The answer is 22. Right? if you mean (2/3) * 13 or 2 / (3*13) i believe according to both your answer is wrong Is that (2/3)*13? If so, then (2*13)/3= something other than 22. Or if it is 2/(3*13) = it
