Answer:
127
Step-by-step explanation:
The sum of 7 terms of the series 1 +2 +4 +... with first term 1 and common ratio 2 is given by ...
Sn = a1 × (r^n -1)/(r -1) . . . . . . first term a1, common ratio r
S7 = 1 × (2^7 -1)/(2 -1) = (128 -1)/1 = 127

Answer:
1433 m^2
Step-by-step explanation:
Area of the triangle
16 x 16 x 1/2 = 128
Area of the hexagon
A = 
a is a side of the hexagon
A = 
= 665.1075101...
There are 6 triangles so...
128 x 6 = 768
Therefore the surface area is
665.1075101... + 768 = 1433.10751 m^2
24 is a multiple of 6.
24 is a factor of 48.
24 is neither a multiple nor a factor of 36.
It is quantitive and from that, I'm pretty sure it's discreet, sorry if the second part isn't very helpful.
