Answer:
A. 4(4a + 18)
B. 8(2a + 9)
Step-by-step explanation:
<u><em>We know that</em></u> :
16a = 4×4×a
72 = 4×18
Then
16a + 72 = 4×(4a) + 4×(18)
= 4 × (4a + 18)
On the other hand,
16a = 8×2×a
72 = 8×9
Then
16a + 72 = 8×(2a) + 8×(9)
= 8 × (2a + 9)
First, you must find the side length. It is a hexagon so there are 6 sides. You take the perimeter by 6 48/6 and get 8. Then plug it into formula (3 sqrt 3)/2 a^2 where a is side length. Plug into formula and get an answer of 166.28 in^2
3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer
