Bla bla bla your answer is x=4.95
12. I need the graphs to answer it
11. y = 1/2x - 1
10. The first graph is the best
Answer:
I don't know the answer but i recommend a website called cymath. It is a calculator to any equation and demonstrates the procedures.
Answer and Step-by-step explanation:
We are told that AB is equal to 3x + 1.
BC is then half of AB, or
.
AC is then 4 less than BC, or 
To find the perimeter, we add all of these together.
3x + 3x/2 + 3x/2 = 6x
1 + 1/2 + (1/2 - 4) = -2
The final answer is 6x - 2.
