Answer:
41x² - 27x + 27
Step-by-step explanation:
Perimeter of Rectangle:
= 2(20x²-12x+4) + 2(5x²-5x+15)
= 40x²-24x+8 + 10x²-10x+30
= 50x²-34x+38
Perimeter of Triangle:
= 6x²+6x+3x+3+3x²-2x+8
= 9x²+7x+11
Difference:
(50x²-9x²)+(-34x+7x)+(38-11)
= 41x² - 27x + 27

C=20m+15 represents the relationship between cost and number of months.
Step-by-step explanation:
Given, 
Initial fee charged by gym = $15 
Per month fee of gym = $20
Let, 
m be the number of months.
C be the total cost for m months.
Total cost = Initial fee + Per month fee*number of months
C = 15+20m
C=20m+15
C=20m+15 represents the relationship between cost and number of months.
