Hi. i hope you had the time to stumble across my question and hope you can solve it because i can't! you:

1.6f+0.4j-13

In order to simplify this problem you would need to combine all like terms

-1.3f+0.4j-12-1+2.9f (first we could put together -12-1=-13)

-1.3f+0.4j-13+2.9f (we would then put together -1.3f+2.9f=1.6f)

1.6f+0.4j-13 would be you simplified equation

f is the midpoint of
