Answer:
10(7b-3c)
Step-by-step explanation:
Area 512
area a = s^2
a = (8^(3/2))^2 = 8^((3/2)*2) = 8^3 = 512
1x18 2x24
2x9. 3x14
3x6. 6x7
6x3
GCF 6
7 and 1/2+6 and 3/4+7 and 1/3=7+1/2+6+3/4+7+1/3=7+6+7+1/2+3/4+1/3=20+1/2+3/4+1/3
convert bottom nubmer to same (12)
1/2 times 6/6=6/12
3/4 times 3/3=9/12
1/3 times 4/4=4/12
20+6/12+9/12+4/12=20+19/12=20+1+7/12=21+7/12=21 and 7/12
answer is 21 and 7/12 hour or 21.58 hour or 21 hour and 35 minutes
