Perform the indicated operation. Simplify if possible.
(2) / ( x + 4) + (9) / (5x + 20 )
(19) / (5x + 4)^2
(11) / (5x + 4)
(47) / ( 5x + 4)
(19) / ( 5x + 4)
2 / (x+4) + 9 / [5(x+4)]
= 2(5) / [5(x+4)] + 9 / [5(x+4)]
= (10+9) / [5(x+4)]
= 19 / [5(x+4)]
= 10/(5x+4)
The remaining problems are all in there most simplified form.
