<span>f(x)=5x+3/6x+7
This means that f(6/x) = [</span>5(6/x)+3] / [6(6/x)+7] = [ 30/x +3 ] / [36/x +7]
If we assume x≠0 , f(6/x) = [30 +3x]/ [36 + 7x]
g(x)=√<span> [ x^2-4x ]
</span>
g(x-4) = √ [ (x-4)^2-4(x-4) ] = √ [ x² -8x +16 -4x +16 ] = √ [ x^2-12x +32]

im terrible at explaining so-
Answer:
this trinomial is prime, and cannot be factored.
Step-by-step explanation:
when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.
1 * 19 = 19
there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
Answer:
56
Step-by-step explanation:
This problem can be solved b using a combination. We're using a combination for this because the order in which you would pick the songs doesn't matter. To solve, we would plug in the number of songs we want to download, in this case 8, into the n value of the combination. Then we would plug in the number of songs that we can pick, in this case 3, in the r value of the combination. Solve the combination and we get 56.
