Emma says that the product of a 3 digit number and a 1digir number will be either a 3 digit number or a 4 digit number. does emma's statement make sense? explain

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^
