Answer:
Step-by-step explanation:
1.5m
(2500mm)/(1000 mm/m) = 2.5m
(850mm)/(1000 mm/m) = 0.85m
4.8m
Add the number of meters:
1.5 + 2.5 + 0.85 + 4.8 = 9.65m

Determine the surface area
The figure is made up of two cuboids and the surface area of a cuboid is:

Because the bottom part of the upper piece is not visible, the area is calculated as:

This gives:


For the bottom piece:
We calculate its area as
. However, the area of the invisible part will be subtracted.
So, we have:


The total surface area is:


Answer:
b. 6|x|
Step-by-step explanation:
√(36x²) = √36√(x²)= 6|x|
Because √ from the number can be only positive.
Answer:
x = 
Step-by-step explanation:
Let the number be x
x + 2x² = 10
Factorize x + 2x²
x(1 + 2x) = 10
Divide both sides by (1 + 2x)
x =
