Answer:
A = 72, P = 38
Step-by-step explanation:
Area can be found by getting the area of the overall figure, and then subtracting the blank space in the corner
12 * 7 = 84
3 * 4 = 12(invisible rectangle in top right)
84 - 12 = 72
Perimeter can be found by adding all of the sides
12 + 7 + (12-4) + 3 + 4 + (7-4)
The numbers in brackets are the unlabeled sides on the top and left.
I'm assuming you need to evaluate/simplify the equation, so you need to isolate/get x by itself in the equation:
2(3x + 1) = 11 Divide by 2 on both sides
3x + 1 = 
[11/2 or 5.5] Subtract by 1 on both sides
[make the denominator the same to combine fractions]
3x = 
Divide by 3 on both sides
x =
