Compatible Ram and additional SSD upgrade

[The_14k]

So, my Laptop is:

HP Pavillion Gaming Laptop 15-cx0140TX.

1TB HDD

8GB RAM,

no SSD,

core i5 8th

4GB graphics card

And I felt like upgrading the ram and storage.. So my question is which RAM should I buy, how many storage capacity of RAM will my system support and most importantly is there an additional space for adding SSD slot if so what size and model should I use?
