The first answer is C. I did this by subtracting 40 from both sides which gave me: -3a=-63 Then I divided -3 from both sides which gave me a to equal 21.Â
The second answer would be 15. I did this by subtracting 3 from both sides which gave me: 1/5n=3 Then I multiplied by 5 on both sides. I took the reciprocal of 1/5 which is 5 and it gave me n to equal 15. I hope this helped you! Let me know if you have any questions!Â
Answer from: Quest
area = length x width
length = 2 x width
32 = 2 x width x width
32 = 2 x width^2
36 = width ^2
width = 6
length = 12
area is 32
perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
