Question

What is the length of side BC of the triangle? Make sure to show all of your work!

Answer 1

For other ppl looking at this question here's the answer.
First you have to put
`x+8` and
`2x-1` equal
Like this
`x +8=2x-1`
Then you have to get x on one side
So Add 1 to both sides which cancels out the
`-1`
And you have
`x+9=2x` left
Then subtract x from both sides
And you get
`x=9`.
hope this helps you; if you need help pm me :).

Answer 2

you have to first get the x by its self by canceling it out so subtract 3 and what you do to one side you do to the other. so that means that -3(-3) two negatives = a positive so thats 6 so what you should have now is x+6
