Answer:
84
Step-by-step explanation:
they are all equal sides so what you'd do is 28+28+28= 84
It is just doubled the number before so the next number would be 160, then it would be 360, 720, etc..
First, replace all variables with the given values.
12(9) + 9(2) + 2(12)
This should then equal 150, then the formula says to multiply this answer by 2. Doing so, should give a final answer of 300.
