Answer:
G. 7600 
Step-by-step explanation:
Step 1: Deconstruct the shape
2 rectangles with dimension of 50 cm x 20 cm
2 rectangles with dimension of 40 cm x 20 cm
2 rectangles with dimension of 40 cm x 50 cm
Step 2: Find surface area of the shapes
2(50 x 20) = 2000 
2(40 x 20) = 1600 
2(40 x 50) = 4000 
Step 3: Add the surface areas together
2000 + 1600 + 4000 = 7600 
Therefore the surface area is 7600
and the answer is G.
Answer:
f(1) = 5, f(2) = 8, f(3) = 11
Step-by-step explanation:
Common difference refers to how you get from one value in the sequence to the next.
If f(0) = 2, f(1) = 2 + 3 = 5 etc
Please refer to the above attachment
Sqrt -13 = sqrt13 i
sqrt -26 = sqrt2 * sqrt13i
sqrt-13 * sqrt -26 = sqrt2 * 13* i^2 = -13 sqrt2 (because i^2 = -1)
answer is -13 sqrt2
