The two outer "strands" should be parallel and the rungs should be perpendicular to the strands.
What do you need information on??
-18v^2 + 23v^2 =
In order to find the solution to this problem we are gonna add like terms.
-18v^2 + 23v^2
= 5v^2
A negative plus a positive results to a positive
Step-by-step explanation:
In the picture.
I hope that it's a clear solution and explanation.
