Answer :

Answer:

3*(x-2)

Step-by-step explanation:

You should notice that : YW=YB+BW

  • YB= x+3
  • BW= 2x-9
  • YW= x+3+2x-9

              = 3x-6

              = 3*(x-2)

If YB is x+3 units long and BW is 2x-9 then the length of YW will be 3(x-2) units long.

What is a parallelogram?

A parallelogram is a shape in which opposite sides are parallel to each other.

How to find the length of the diagonal?

From the figure we can see that the diagonal YW=YB+BW

YB=x+3

BW=2x-9

YW=x+3+2x-9

YW=3x-6

YW=3(x-2)

Hence the length of YW will be 3(x-2) if YB=x+3, BW=2x-9.
