To solve 5(2^x + 4) = 15 first divide each side by

5

Step-by-step explanation:

if you divide by 5 on both sides then you would just be left with 2^x+4=3 and it would save you the trouble of having to simplify later on. hope this makes sense

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
