Elemantary school so area=legnth times width to get greatest area, make legnth as close to width as possible in measure
to get least area, make legnth as far away from width as possible in measure perimiter=2 times legnth+2 times width=2 times (legnth+width) 18=2 times (legnth+width) divide 2 9=legnth+width find closest and farthest 1+9 is farthest 4+5 is closest
areas=legnth times with 1 times 9=9 4 times 5=20 differnce is subtract 20-9=11
answe is 11 (note I didn't use decimals since the user is supposedly in elemenatry school)
As the liquid gets closer to the same temperature as the room, it cools down slower. If you put an glass of hot cocoa in a really cold room, it'll decrease really fast until it's around the same temperature as the room
First you raise the expressions in the parentheses to their powers. Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases).
