Write an expression for the perimeter of the triangle shown below: The answer choices are:
6.9x − 16
6.9x + 16
0.1x − 16
0.1x + 16

0.1x-16

Step-by-step explanation:

just add all of the xs up and then the numbers up

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

3 4 7 12 19

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
