Hi there!
Here are all the steps into simplifying this expression :
(4 × 2) + 15x + 49
Do the multiplication first → 4 × 2 = 8
8 + 15x + 49
Add the similar terms together → 8 + 49 = 57
15x + 57
Since there are no longer similar terms, the expression can not be simplified anymore and you are left with this expression as an answer :
15x + 57
There you go! I really hope this helped, if there's anything just let me know! :)
