133=x + (x+5) + (x+14)
133 = 3x+19
3x=114
x= 114/3 =38
5+38 =43
38+14 =52
check: 38 +43 +52 = 133
3 sides are : 38, 43 & 52
If we take both sides of the equation
and <em>multiply either expression by 3</em>, the equality becomes

Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.
I think it's B and D because both of them will give you the same answer which is 2.71 but turn it into fraction.
