15.6 - 12.3 me my homework is due in 3

3.3 would be the answer.

Step-by-step explanation:

This is because 15 - 12 is 3 and 6 - 3 is 3, therefore, when you add the decimal in between again, you get the answer.

-4

step-by-step explanation:

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
