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 [tex] \frac{5x-15}{x^{2}-3x-28} [/tex]
6. third or[tex] \frac{4x+25}{x^{2}+5x+4} [/tex]
7.the answe ris x+3 since it can be factored out of the 5x+15 tingie (second )
8. fourth or [tex] \frac{x^{2}+4x}{4} [/tex]
9. fourth or [tex] \frac{2y+6}{9y-7} [/tex] times [tex] \frac{3}{2} [/tex]
10. third or [tex] \frac{(x+3)(x+8)}{(x-8)(x-8)} [/tex]
11. second or [tex] \frac{x-5}{x-4} [/tex]
12. third or 11(x+7)=60
