Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2
The surface area of the square pyramid is 96 sq. mi.
<em>Given:</em>
side length (s) = 6 mi
slant height (l) = 5 mi
<em>*image of a typical </em><em>square pyramid </em><em>is shown in the attachment below.</em>
<em>Recall:</em>
Formula for surface area of square pyramid (SA) =
Where,
area of the base = sq mi
perimeter of the base = mi
slant height = 5 mi
Plug in the values
The surface area(SA) of the square pyramid is 96 sq. mi

Answer:
0.45 m, 0.63 m, 0.72 m
Step-by-step explanation:
Let the three parts of the line be 5x, 7x and 8x
Therefore,
5x + 7x + 8x = 1.8
20x = 1.8
x = 1.8/20
x = 0.09
5x = 5*0.09 = 0.45 m
7x = 7*0.09 = 0.63 m
8x = 8*0.09 = 0.72 m
