Protons are shown by a plus sign (+) and neutrons are shown by a circle (o).

Both B and C are correct.

i’ll just s take the points thxs

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.

you!
