Plug n = 1 into the expression 20-9n and we get
20-9n = 20-9*1 = 20-9 = 11
So 11 is the first term of the series that we add up. Therefore the answer must be choice C, which has 11 listed as the first term added
Answer:
x = -1
Step-by-step explanation:
6 − 4x = 6x − 8x + 8
Combine 6x and −8x to get −2x.
6 − 4x = −2x + 8
Add 2x to both sides.
6 − 4x + 2x = 8
Combine −4x and 2x to get −2x.
6 − 2x = 8
Subtract 6 from both sides.
−2x = 8 − 6
Subtract 6 from 8 to get 2.
−2x = 2
Divide both sides by −2.
Divide 2 by −2 to get −1.
Hope this helps and have a great day! =D

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:
