F(n) of the sequence is: 2.5
2 x 2.5= 5
5 x 2.5= 12.5
Etc.
Answer:
2/3
Step-by-step explanation:
The slope of a line can be computed as:

where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(0,1) and (3,3)
Therefore, the slope of the line is

Two lines are said to be parallel if they have same slope: therefore, a line parallel to the one shown should also have slope of 2/3.
3x-x=10+2
3x-1x=12
2x=12
2÷2. & 12÷2 =6
x=6
Split the composite figure in two
a rectangular prism and a isosceles triangular prism
when u have the figures separated use the formulas for the each
rectangular prism formula- A=2(wl+hl+hw)
isosceles triangular prism formula- a= 2b+ph
add both surface areas to get the answer
