The sum of two adjacent sides is 11 inches, so the long sides are 9 inches. The "unknown number" must be 12.
11 is the answer to your question.
2×11=22

Answer:
f(5) = -2
Step-by-step explanation:
You look on the x-axis for 5 because f(5) means let x = 5. Then go down to the graph (the red zig-zaggy line) At the red line (you're still directly under the 5) look over to the y-axis to find the value. That's your answer. It is -2. The point (5, -2) is on the red graph.
f(5) = -2
I believe the anwser would be -B
