The original height of the plant is 20 inches, and each week for 4 weeks its height increases by 2h inches, so at the end of 4 weeks its height would be:
20 + 4(2h) = 20 + 8h
Now for the next two weeks the plant grows in height by h inches each week, so we need to add a further 2h inches to the equation. Thus the expression that shows the height of the plant after 6 weeks is:
20 + 8h + 2h = 20 + 10h, therefor A is the correct answer

Answer:
Patricia = $47.5 ;
Greg = $57.5 ;
$10
Step-by-step explanation:
Perimeter of a rectangle : 2(l + b)
Patricia :
7ft * 12 ft
2(7 + 12) = 2(19) = 38 ft
Total fencing cost :
1.25 * 38 = $47.5 ft
Greg:
8ft by 15ft
2(8 + 15) = 2(23) = 46ft
Total fencing cost :
1.25 * 46 = $57.5
Difference in cost :
57.5 - 47.5 = $10
