I would say 3 because terms are separated by a plus or minus sign and there are 2 subtraction signs separating 3 expressions.

zavuch27 [327]

What you have so far is perfect. You started with the given statements and then use the definition of midpoint to show that each piece is equal to one another.

From here, use the transitive property

We combine these two statements

  • WX = XY
  • XY = YZ

into the following

WX = YZ

So we can effectively say WX = XY = YZ meaning the segments WX, XY and YZ are all the same length.

Through similar logic, we can chain together

  • VW = WX
  • WX = XY

to get VW = XY

-------------

Consequently this means VW, WX, XY, and YZ are all the same length

Let's call that length m.

m = length of segment VW = length of WX = etc etc

This means,

VY = VW+WX+XY = m+m+m = 3m

and

WZ = WX+XY+YZ = m+m+m = 3m

Both VY and WZ are exactly 3m units long, therefore, VY = WZ

I'm not very good with square roots. Can someone please explain it to me and help me understand how to do them?

A square root is Is a number times it's self. Like 2 is the square root of 4, because 2*2=4. 3 is the square root of 9, because 3*3=9....... And 7 is the square root of 49, because 7*7=49.
