For me personally, the easiest way to do this is by isolating the x² term, and finding the square root of both sides. The hardest way (well actually, the longest way) would be to use the quadratic formula. It just complicates things unnecessarily.
Answer:
1260 inches squared
Step-by-step explanation:
Bottom: 24*6=144
Bottom front: 24*12=288
Bottom back: 24*12=288
Left side: 6*2=72
Right side: 6*12=72
Left top: 6*15=90
Right top: 6*15=90
Top front: (24*9)/2=216/2=108
Top back: (24*9)/2=216/2=108
144+288+288+72+72+90+90+108+108=1260
Answer:

Step-by-step explanation:
1,200/316 = 3.79746835 = 3 people
-22 = -2x + 9
-31 = -2x
-31/-2 = x
x = 15.5
