Answer:
422 cm²
Step-by-step explanation:
Surface area of the composite figure = (surface area of the upper cuboid + surface area of lower cuboid) - 2(base area of the lower cuboid)
Surface area of composite figure = 
Upper cuboid has the following dimensions:

Lower cuboid has the following dimensions:

Plug these values into the formula
Surface area of composite figure




Surface area of composite figure = 422 cm²
Answer:
3n - 4
Step-by-step explanation:
Both are correct because .5 is ten percent of 5. And the increase is only a half of a percentage point.
The graph is crossing x-axis at the points
a) -1
b) 5
c) 8
This means x + 1, x - 5 and x - 8 are the factors of the given polynomial. We can express the polynomial as the product of its factors. So the given polynomial can be expressed as (x + 1)(x - 5)(x - 8).
Thus, the correct answer to this question is option D
