For number one you should get 6√3
5.4 because the 9 bumps it to 5.35.
And the 5 bumps it to 5.4.
the surface area of that rectangular prism is 247.5.
The answer is c.
I will explain
p - 2r = q
1. Move variable to the right by adding it’s opposites on both sides
p - 2r + 2r = q + 2r
2. Eliminate the opposites (-2r and +2r)
p = q + 2r
Do 45 times 360 and you will get d as your answer
i hope this helped
