Answer:
8x - 20
Step-by-step explanation:
3(x - 6) + 4 + 5x - 6 
Distribute 3 to (x - 6)
3(x) - 3(6) + 4 + 5x - 6
3x - 18 + 4 + 5x - 6
Simplify:
3x + 5x - 18 + 4 - 6
8x -18 - 2
8x - 20

just do the number +1 and ×4
Perimeter = 2 * 85 + 2 * 125 = 420
85 * 125 = 10,625 area
70 by 140 = 420 perimeter
70 * 140 = 9,800 area
