jhonyy9 (jhonyy9):

width time length =area ok ?

OpenStudy (anonymous):

jhonyy9 (jhonyy9):

first for smaler :

jhonyy9 (jhonyy9):

came on please i like help you

OpenStudy (anonymous):

4x/(x^2 + 7x + 10)

OpenStudy (anonymous):

4x(x^2 + 7x + 10)* sorry accidental slash

OpenStudy (anonymous):

and x(x+4)

OpenStudy (anonymous):

x(x+5) I mean

jhonyy9 (jhonyy9):

yes x(x+5) for the smaler so now for larger

OpenStudy (anonymous):

for larger 4x(x^2 + 7x + 10)

jhonyy9 (jhonyy9):

yes right so how can you calcule ratio of two numbers like A and B ?

OpenStudy (anonymous):

A and B?

OpenStudy (anonymous):

Wait wouldnt you distribute first?

jhonyy9 (jhonyy9):

So then it would be x^2 + 5x and 4x^2 + 28x + 40x

jhonyy9 (jhonyy9):

not is necessary make these calcules came on please answer my question and will get easy the right answer
