Answer:
280.6 
Step-by-step explanation:
<u>find the length of each side:</u>
you're only given h = 9 m
the formula for h is
, where a is a side length of the hexagon
plug h in:

a ≈ 10.392 m
<u>now find the area of a triangle:</u>
1/2 (10.392)(9) = 46.764 
multiply that by 6 and you get 280.584 ≈ 280.6 
you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: 
Answer:
a) x = 2
b) x = 4
Step-by-step explanation:
a = (b₁ + b₂)/2 * h
----------------------------
a)
48 = (10 + x)/2 * 8
Divide both sides by 8
6 = (10 + x)/2
multiply both sides by 2
12 = 10 + x
Subtract 10 from both sides
2 = x
x = 2
---------------------------------
b)
18 = (7 + 2)/2 * x
18 = 4.5 * x
divide both sides by 4.5
4 = x
x = 4

I hope my answer helped!
Answer:
120 baseball cards
Step-by-step explanation:
15 × 2 = 30
30 + 10 = 40
40 ÷ 1/3 = 40 × 3/1 = 120
Therefore there were 120 cards in the back
<em>I just did the inverse of each process starting from the last step and ending at the first</em>
The answer is x = 4 as it satisfies both inequalities :)
