Answer:
1) s=15
2) 15, 21, 21, 15, 30 from left to right
Explanation:
First you turn this into an equation: s+6+s+6+s+s+2s
Collect like terms: 4s+ 12 + 2s
Simplify: 6s+12
Bring back into a full equation: 6s+12=102
Simplify= 102-12=6s
90= 6s
90/6=s
s=15
Then bring back into sides: Left side and right sides are 15 as s= 15
15+6= 21 so both top sides are 21
2×15=30
So it goes in the order from left to bottom clockwise:
15, 21, 21, 15, 30
