Which expression equals 24? A) (2 + 4)(3) B) (4 x 2)(3) C) (4 + 3) - 2 D) (4 - 2) + 3

alones (alones):

Alright let's check each option..starting from A. \[\ (2+4)(3)\] \[\ (6)(3)\] \[\ 18\] So, choice A won't work.

alones (alones):

For \(\ (4 x 2)(3) \)"x" stands for multiplying ? @khameleon

alones (alones):

Alright let's go on to C. \[\ 4+3−2\] \[\ 7−2\] \[\ 5\] So C also would be wrong.

alones (alones):

OKay, let's look at the last option \(\ (4 - 2) + 3\) That would also be \(\ 5\) \[\ 4−2+3\] \[\ 2+3\] \[\ 5\]

alones (alones):

Alright so the right answer would be\( ~B)~ (4 x 2)(3) \) Since \( (4)(2)(3)\) \[\ (8)(3)\] \[\ 24\]
