Answer:
Solution given;
slant height[l]=32km
side of equilateral triangle (a)=14km
now
total surface area of triangular pyramid =
area of base triangle +3 area of traingular faces
=√3/4 a²+3×½×{b×l}
=√3/4 14²+3/2×{14×32}
=756.87=757 km² is a required surface area.
Answer:
B
Step-by-step explanation:
When taking the first equation (x+2)(x-4) / (x-4)(x+4), the x-4 on top and bottom cancel out, leaving us with (x+2) / (x+4) which is B.

Answer:
1300
Step-by-step explanation:
Given that :
Number of sections = 8
Number of seats per section, x ;
150 ≤ x ≤ 200
The possible Number of seats in the auditorium :
Number of seats per section * number of sections
150 * 8 ≤ x ≤ 200 * 8
1200 ≤ x ≤ 1600
The possible Number of seats will lie within 1200 and 1600
From the options, only 1300 lie within this range
