Pls help, how do I find the variables?

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.

b is the right answer

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)
