write it this way ....
(x^2+4x-5)/(5x-5) * 5x/(x+5)
= (x+5)(x-1)/(5(x-1)) * 5x(x+5)
= x , x ≠ 1,-5
How many different vacation plans are possible when choosing one each of
12 destinations, 3 lengths of stay, 5 travel options, and 4 types of accommodations
The problem is wrote like this
x^2+4x-5/5x-5*5x/x+5
I have tried to work it. but canot get it.
Did you not look at my solution?
Cassie, please do not post a new question as a response to somebody else's problem.

as to your problem ...
what is 12x3x5x4 = ??
the problem is x^2 plus 4x-minus 5 over5x-5 time 5x over x+5 without parenthesis.
x^2 plus 4x-minus 5 over5x-5 time 5x over x+5
has to be written with parenthesis in this format to have the proper order of operation
That is why I retyped it as
(x^2+4x-5)/(5x-5) * 5x/(x+5)
(x^2+4x-5)/(5x-5) * 5x/(x+5) is equivalent to
x^2 plus 4x-minus 5 over5x-5 time 5x over x+5
Problem: (X^2+4X-5)/(5X-5)*5X/(X+5)
Solution:(X-1)*(X+5)/5(X-1)*5X/(X+5)=(X+5)/25X/(X+5)=(X+5)*(X+5)/25X=(X+5)^2/25X.
The parenthesis are neccessary for clarity. Notice that the numerator and a portion of the denominator are factored.
