Answer:
240in
Step-by-step explanation:
Total surface area of a square based pyramid is expressed as
TSA = 1/2pl + B
p is the perimeter of the base
p = 4L
p = 4(2)
p = 8in
l = 4in
B is the base area = 2 * 2 = 4in^2
TSA = 1/2 * 8 * 4 + 4
TSA = 16 + 4
TSA of one game piece = 20in
Since we have 12 game pieces, total surface area will be 20 * 12 = 240in

<em>A. x ≤ - 9 or x ≥ 9</em>
- Step-by-step explanation:
<em>x² ≥ 81</em>
<em>| x | ≥ 9</em>
<em>x ≥ 0 => x ≥ 9 => x ∈ [ 9 ; + oo)</em>
<em>x < 0 => x ≤ - 9 => x ∈ ( -oo ; - 9 ]</em>
<em>x ∈ ( -oo ; - 9 ] ∪ [ 9 ; + oo)</em>
Answer:
