Hold on, I'll try to write the problems out
The four X's are supposed to be spaced out between the lines. You're supposed to match each model with it's expression. The regular line represents the variable
the x btween lines matches with 4x.. as u see there are x's and red line is above all of them so u have to add all 4 of them.. x+x+x+x = 4x
Okay, thanks, now to figure out the rest of them
ok good.. let me know if u need help
thanks, its still a little a little hard to understand and I don't know how to do the other ones
hmm just look on the information given to u.. and red line tells u what part u have to find..
Is the first one x-4?
hmm no look .|dw:1348839749754:dw| now look the above line u have to find the equation of that part.. now look below the middle line u see more then half is 4 and the rest is x. and u have to find the value of whole line so 4+x
Ohhh so the first one is X/4?
nooo.. u have to find the value of whole line half part is 4 and rest half is x.. to get the full line u have to add both
you are talking about the first question in ur doc? right?
Yeah, it's the same as the one I drew
