Please perform each operation and reduce answer. Thanks!
a. (13x^2)/(15) + (3x^2)/(10)
b. (3x+1)/(3x)  (x+3)/(2x)
c. (6x^3y^2)/(5x^6y) ((times)) (10xy)/3
d. (x3)/(x+4) ((divided by)) (x+1)/(2x+8)
p.s. you don't have to work all of these, just as much as you want to do. : )

Best ResponseYou've already chosen the best response.0a: You need common denominators. I'd try 30. \[{13x^2 \over 15 }*{2 \over 2} + {13x^2 \over 10} * {3 \over 3} ={{26x^2 + 39x^2} \over 30}\] b. Ditto with 6x c. and d are different beasts.
