Check the picture below.
as we can see, the triangular prism is really just 3 rectangles and 2 triangles stacked up to each other at the edges, so if we simply get the area of each of those five figures and sum them up, that's the surface area of the triangular prism.
you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B

Answer:
Step-by-step explanation:
let x be the value of the denominator , then fraction is
adding 1 to numerator and denominator , gives
=
= ( cross- multiply )
2(x - 3) = x + 1
2x - 6 = x + 1 ( subtract x from both sides )
x - 6 = 1 ( add 6 to both sides )
x = 7
then original fraction
= =
