just answers since long and many simplifiction
it's like doing those multiplication memory things that had like 100 questions but now with algebra fractions
5. fourth or \(\frac{5x-15}{x^{2}-3x-28}\)
6. third or\(\frac{4x+25}{x^{2}+5x+4}\)
7.the answe ris x+3 since it can be factored out of the 5x+15 tingie (second )
8. fourth or \(\frac{x^{2}+4x}{4}\)
9. fourth or \(\frac{2y+6}{9y-7}\) times \(\frac{3}{2}\)
10. third or \(\frac{(x+3)(x+8)}{(x-8)(x-8)}\)
11. second or \(\frac{x-5}{x-4}\)
12. third or 11(x+7)=60
