Answer:
30x - 18
Step-by-step explanation:
6 x 5x = 30x because its basically the same thing as 6 x 5, but with an x at the end
6 x (-3)= -18
if you havent done negative multiplication yet, then you can do 6 x 3=18 and add the minus sign before the 18
im not sure if that makes sense, but i hope it helped:)
