0.36363636363 is the answer
You just need to foil. 2x times 4x times 2x times 36 times 24 times 4x times 24times 36. then solve.
The answer is 216 cubic feet. How? All you have to do is multiply every number then divide it by 2. Like this: 2*12*18=432. 432/2= 216 cubic feet.
yea they're equivalent cause to solve the second equation sqrt of x+1 plus 3 equals 8 you must subtract 3 from both sides and when you do that you get sqrt of x+1=5 and thats the same as the first equation
