Best ResponseYou've already chosen the best response.0top: x+3 right: x^23x left: x+7 bottom: 3x3

Best ResponseYou've already chosen the best response.0Okay! Perimeter is defined by all of the sides added together, right?

Best ResponseYou've already chosen the best response.0So: \[55=(x+3)+(x^23)+(x+7)+(3x3)\] 55, the perimeter is equal to all of the sides added together! We can combine like terms...

Best ResponseYou've already chosen the best response.0So then you have \[55=x^2+5x+4\] I think.

Best ResponseYou've already chosen the best response.0It says i need more than one answer, one for each side

Best ResponseYou've already chosen the best response.0Well if you solve for x, then you put x back into the equation for each side. Does that make sense?

Best ResponseYou've already chosen the best response.0what is x? then i take that and put in each different equation?

Best ResponseYou've already chosen the best response.0Yes. I can help you solve for x.

Best ResponseYou've already chosen the best response.0So, you have 55=(x+3)+(x^2−3x)+(x+7)+(3x−3). This simplifies when you combine like terms to 55=x^2+2x+7. Can you solve it from that point by factoring or do you need more help?

Best ResponseYou've already chosen the best response.0I dont know, what do i do with 55? i can only solve the other side

Best ResponseYou've already chosen the best response.0Well, we can set the expression equal to zero: Move the 55 over to the right. So now, we have 0=x^2+2x48. Do you see how I got that? Next, try to factor this; it works out nicely. Should give you two answers.

Best ResponseYou've already chosen the best response.0Yes! Okay, so we're talking about distance here. can we have a negative distance? Which solution do you think we should use?

Best ResponseYou've already chosen the best response.0Yes. So, what are your dimensions if you plug in x=6?
