3 times a number plus 5 is the equal to the same number increased by 17. what is the number

The number is 6

Step-by-step explanation:

Let the number be x

3 times a number plus 5 =  3x +5

Same number increased by 17 = x + 17

3x + 5 = x + 17

3x -x  + 5 = 17

2x + 5 = 17

2x = 17 - 5

2x = 12

x = 12/2

x = 6

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
