assuming you mean
(4x^3-x)/((2x+1)(6x-3))
= (x(2x-1)(2x+1))/(3(2x+1)(2x-1))
= x/3
= 3333
well,
7 men for 7 hrs for 1 day = 1 work unit
7 men for 1 hr for 1 day = 1/7 wu
1 man for 1 hour for 1 day = 1/49 wu
5men * 5hrs * 5days = 125/49 wu
or, just do the ratios in-line
(5/7)(5/7)(5/7)=(5/7)^3*(7) = 125/49
The value of 4x^3-x/(2x+1)(6x-3)
when x=9999
If 7 men working 7 hrs a day for each of 7 days produce 7 units of work, then the units of work produced by 5 men working 5 hrs a day for each of 5 days is?
Pls help***
