Simplify this expression

D, 15x^3+30x

Step-by-step explanation:

when multiplying values with exponents, on ones with x, imagine it as x^1 so when multiplying with exponents we add them together, so 1+2=3

then 6 times 5x is simple

i hope this helps u pls give a brainliest and a thx ;)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
