Which two ratios form a proportion?

C

Step-by-step explanation:

You can’t multiply anything to make A work

Nor B

C you can multiply by 3

D you can’t do anything.

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
