how many polygons make up this prism?

6 polygons

Step-by-step explanation:

we know that

The number of polygons that make up this prism is equal to the number of faces it has.

The rectangular prism of the figure has 6 faces, so there are 6 polygons.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
