Prism A and Prism B have the same volume. Which could be the dimensions of Prism B?

c. 4 1/4 pounds

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^

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
