Best ResponseYou've already chosen the best response.0or Im sorry dont multiply by two, just solve for x and plugin the x in the equation for line CD and you have your answer.

Best ResponseYou've already chosen the best response.0use the equation i gave you above.

Best ResponseYou've already chosen the best response.0you see that both line segments CD and AD are congruent, therefore you can set them equal to each other and solve for x.

Best ResponseYou've already chosen the best response.0oh ok.so then i would multiply the 2x and 4x together?

Best ResponseYou've already chosen the best response.0no you will need to use the opposite operations in order to isolate x.

Best ResponseYou've already chosen the best response.0no not divide, try again.

Best ResponseYou've already chosen the best response.0you can also see it as 4+2x = 4x

Best ResponseYou've already chosen the best response.0but how does that = 4x?

Best ResponseYou've already chosen the best response.0no not add look at you signs

Best ResponseYou've already chosen the best response.0the line segment CD = AD therefore they are equal.

Best ResponseYou've already chosen the best response.0the two lines you drew in the middle of them means they are the same length.

Best ResponseYou've already chosen the best response.0so im not understanding. im so sorry. how do i solve the problem then?

Best ResponseYou've already chosen the best response.0How do you think you would attempt it? I've pretty much given you all of the information and even how to setup the problem.

Best ResponseYou've already chosen the best response.02x+4=4x . i multiply the 2x and 4x to get 8x?

VeritasVosLiberabit

Best ResponseYou've already chosen the best response.0no you need to subtract 2x from 4x

Best ResponseYou've already chosen the best response.0rearrange your equation to see this better. 4+2x = 4x

VeritasVosLiberabit

Best ResponseYou've already chosen the best response.0write your whole equation.

VeritasVosLiberabit

Best ResponseYou've already chosen the best response.0now subtract 2x from both sides of your equation.

VeritasVosLiberabit

Best ResponseYou've already chosen the best response.0and rewrite what you get.

Best ResponseYou've already chosen the best response.0not quite. that extra x on the left should not be there so it should be 4 = 2x

VeritasVosLiberabit

Best ResponseYou've already chosen the best response.0now one more step to solve for x

Best ResponseYou've already chosen the best response.0i divide it by 2 right?
