Question

Tolong ya bagi yg bisa

Answer 1

1) 8/(3a+6) x (a+2)/4 = (8a+16) / (12a+24) = 4(2a+4)/4(3a+6) =(2a+4)/(3a+6)
2) a/(x^(2)+ 4a) x a/12 = 6a/(12x^(2) +48a) = 6a/(6(2x^2+8a) = a/(2x^(2) + 8a)

1) m/(m-5) : 3m/(m+4) = m/(m-5) x (m+4)/3m = (m^2 + 4m)/(3m^2 - 15m)
2) 5/ (5^2 - 3m) : 10m/3 = 5/ (5^2 - 3m) x 3/10m = 15 / (250m -30 m^2)
                                   =15/15(15m-2m^2) =1/(15m-2m^2)
