two questions

Jul 3, 2019

1.)  how can I  write notes in two bars; for example: four quarter and two half notes, like this:

2.) How can I press the pedal for more than a measure?
I tried to use this symbol:      but it doesn't affect the sound.

I tried also to use this line:
but it only affects one measure, no less and no more.

How can I do it?
