Answer:
the answer is c) 2n+8
Step-by-step explanation:
This is because the expession applies to every figure when calculating the amount of sides
figure 1- 2(1)+8 = 2+8 = 10
figure 2- 2(2)+8 = 4+8 = 12
figure 3- 2(3)+8 = 6+8 = 14
Yes, the expression is true for every figure, proving that it can solve for the perimeter
hope this helps :)

Answer:
17. 42
18. 12
19. 12
20. 12
Step-by-step explanation:
Simply substitute the given values into the variables. So if m = 6 and n = 2:
7m = 7(6) = 42
6n = 6(2) = 12
mn = (6)(2) = 12
3m - 6 = 3(6) - 6 = 18 - 6 = 12
Pretty sure it’s -2 i’m sorry if it’s wrong tho
